WGSL: Allow matrices as in/out vars in shaders
WGSL only supports scalars and vectors in in/out vars in shaders,
matrices will need to be broken into column vectors and then
put back together at the beginning (or end) of the shader.
Arrays also need to be split, which will be done in another CL.

WGSL: implement == for vectors by wrapping in all()
WGSL's vec comparisons are component-wise, so wrapping the result in a

Remove PoolAllocator push/pop feature
PoolAllocator would manage a stack of memory pools upon client
calling push() and pop(). This made the code unnecessarily complicated.
The feature was only used with nesting of one, to mark the memory
unused after a shader compile.
Fix by removing the push/pop feature. Instantiate PoolAllocator in
places the previous push() was and uninstantiating instead of previous
pop().
This removes the feature where the PoolAllocator would hold on to
the allocated memory in order to reuse it. This is seen as a
progression: the allocator is held by the compiler, the compiler is
held by the shader and each shader typically see only one compile.
Thus the free pages were just leaking unused until the shader was
destroyed. Instead, destructing the PoolAllocator instead of pop()
will donate the memory back to platform/OS, where it is likely
more useful.
To preserve existing Vulkan behavior, add PoolAllocator::reset()
which would mark the memory unused but leave them reserved for the
PoolAllocator.
Removes UB where PageHeader::nextPage would be accessed after
~PageHeader.

Metal: Allow optimization of simple loops
Reimplement the feature to avoid undefined behavior of infinite loops.
Add EnsureLoopForwardProgress rewrite pass that inserts a volatile
variable access to all loops that it cannot analyze as being finite.
Detect loops of form `for (; i <op> x; ++i)` as being finite.
The <op> can be any of <,<=,>,>=,==, != operator.
The i can be int or uint.
The ++i can be -- or ++, -=1, +=1.
This assumes that backends using the feature emit signed int arithmetic
with defined wraparound semantics.
Uses volatile write instead of asm("") due to asm not forcing the
behavior in some compiler versions. The volatile variable access is
defined in C++ as forward progress, and by inheritance this works in
MSL.
Later commits may remove injectAsmStatementIntoLoopBodies if
ensureLoopForwardProgress is appropriate for all use-cases.

[WGSL] Emit sampler types and texture lookup builtins
The split texture/sampler WGSL variables will now have the correct
types corresponding to their GLSL types.
Texture builtins are translated as faithfully as possible. There are
some issues with the translation:
1. Texture builtins using an implicit level-of-detail in a vertex
shader are supposed to sample from the base mip level. Right
now these are translated into WGSL functions that cannot be used
in a vertex shader at all.
2. Some texture builtins that take integer samplers do not have
corresponding WGSL versions, e.g. the sampling GLSL function
texture() takes integer samplers but the mostly equivalent
WGSL builtin, textureSample(), will only take float samplers.
3. A number of GLSL texture builtins are not supported in WGSL
when uses on shadow samplers, e.g. anything with a bias
parameter, an explicit LOD parameter, or explicit gradients,

WGSL: Output samplers, including samplers from structs
This output two WGSL variables for each GLSL sampler, including samplers
in structs. This does not output the correct types for the WGSL
variables, yet, nor does it generate texture access function calls.
It also can't deal with arrays of samplers, which are not allowed in
WGSL.
Note that WGSL does not allow structs containing samplers to be
arguments to a function, like Vulkan, nor does it allowed arrays of
samplers at all, unlike Vulkan. This deals with the former problem the
same way as Vulkan and Metal, by monomorphizing functions that take
unsupported arguments.

matCx2 in WGSL does not match std140 layout and so it needs to

On use it needs to be converted to a WGSL-native matCx2.
This also includes the optimization of an array<matCx2> in a
uniform--when indexing into it, only the indexed element
will be converted to a native matCx2, instead of converting
the entire array and then indexing.

WGSL: support small stride arrays in uniforms
WGSL requires arrays in the uniform address space to have a stride
a multiple of 16.
This CL makes WGSL translator emit wrapper structs for array element
types used in the uniform address space, when the array stride is
not a multiple of 16. The exception is for structs that aren't
an aligned size of 16n, and for any types matCx2, since they are
(or will be) handled in different ways that ensure alignment to 16.
This should leave only f32, i32, u32, and vec2.
See https://www.w3.org/TR/WGSL/#example-67da5de6 for an example
of using a wrapper struct.
This requires converting arrays with a wrapper struct element type
to arrays with an unwrapped element type when they are first used;
this can be "optimized" later for the common case of accessing a
single array element, which can then be unwrapped immediately. This
CL generates WGSL conversion functions when necessary.
After this, the only types that can't yet be used in a uniform
are matCx2 and bools.
This is #2 in

WGSL: @align appropriate struct members in uniforms.
Structs used in the uniform address space need to have certain
members aligned according to the uniform address space layout
constraints (substantially similar to std140).
This CL adds @align annotations where necessary, in structs used
in the uniform address space. Strictly speaking, it's okay to apply
@align annotations to all structs used in the WGSL program, but this
CL uses a pre-pass AST traverser to records all the structs used
in the uniform address space. This is to avoid more unreadable
generated code, and when more transformations are applied to
these structs in future CLs, less generated code overall.
After this, the only types that can't yet be used in a uniform
are matCx2, arrays with stride not divisble by 16 (except when the
array element type is a struct), and bools.
This is #1 in struct translation in

Validate anonymous struct names with namespace
Consider GLSL:
struct { vec4 e; } g;
struct sbbf { vec4 f; };
The struct name validation would fail if user chosen struct name would
clash with a symbol name that ANGLE internally gave to an anonymous
struct.
Fix by importing Name abstraction from MSL backend. A symbol name is
a pair (namespace, string).
Move operator<<(std::ostream &os, const ImmutableString &str)
to sh namespace because that is more natural for operator overloading
name resolution. MSVC works with this.

Avoid reordering structs when separating from func
Avoid reordering structs when separating struct declarations
and function declarations.
Consider:
struct S1 { ... };
struct S2 { S1 a; } f();
SeparateStructFromFunctionDeclarations would insert the S2 to
the beginning of the containg block, so before S1 definition.
Fix by not inserting the structs to the parent block. Instead,
return the nodes from multi-replacement, so that the struct
definition is inserted at the site of the replaced function.

WebGPU: send uniforms to GPU for use in shader
Basic uniforms should now be accessible in the shader during a draw
call, rather than just via glGetUniform*().
This is unoptimized and creates a new GPU-side copy of all the uniforms,
every time any uniform changes.
This sets up the bind group layout for a pipeline and sets the bind
groups in the renderer pass. Right now these bind groups only contain
the default uniform blocks, but in the future will need to contain
textures, samplers, and non-default uniform blocks (UBOs).

Metal: Fix rewritten array variables clashes
It was possible to generate MSL name clashes by declaring arrays,
such as in:
mat3 a[1]
mat2 a_0;
Complex GLSL outputs need to be linearized into primitive MSL types.
This would happen for struct outputs, arrays and matrices. For
these new MSL variables, the translator needs to invent new names
that match, generated from both VS and FS.
The clashes were due to the encoding scheme:
For arrays, the MSL vertex output variable was named with _0 suffix for
the array and _0 for the matrix row 0. In the example above, this
would create a clash since also non-array mat would be linearized
row-wise.
For structs, field `a.b` would be encoded as `a_b`. By selecting
different a and b, clashes could be generated trivially.
It is redundant to encode named semantics in the out variable names. The
only needed element is the discriminator which associates VS variables
to FS variables. Currently this is done by using the user-provided
root field name.
Fix by encoding only the root variable name to the MSL variable name.
The rest of the field discriminators are just a running number.
Each GLSL name `a` is unique. MSL names get fixed suffix form `a_X`,
and thus all of them are unique too.
This is a continuation of following fixes that turned out to be
incomplete:

Metal: SeparateCompoundStructDeclarations fails validation
Consider GLSL:
struct S { int i; } s;
s=s;
SeparateCompoundStructDeclarations would rewrite this to:
struct S { int i; };
S s';
s=s;
The interm rewrite would rewrite the specification and declaration of s,
but not the use sites. The use sites would use the old type, and thus
something that was not in the tree anymore. This would fail the
validation.
This kind of bug was previously fixed for SeparateDeclarations
in commit 18fa02bebf901dd8501de3176f6052ae4ce984be.
Fix by adding the logic to SeparateDeclarations, as it is already
doing almost the exact task, separating `struct S { ..} a, b`.
The separation is tested in GLSLTests.StructInShader and various
other draw tests. These pass with MSL, but these would also fail
validation if that was enabled.

Metal: Fix ToposortStructs validation == failures
ToposortStructs would convert mat, vec, struct == to ANGLE_equals()
calls. However, the functions called were not in AST. This would cause
"Found node calling previously undeclared function
<validateFunctionCall>" validation error and ASSERT.
Mat, vec equality calls would use prelude ANGLE_equals implementations.
The MSL emit already does the conversion from == to ANGLE_equals for
these builtins.
For user-defined structs the logic would be:
- collect struct decls, structs, create equality functions
- toposort
- for each sorted struct:
- insert struct decl
- insert equality function
Move the equality function creation after the toposort:
- collect struct decls, structs
- toposort
- for each sorted struct:
- insert struct decl
- create equality function
- insert equality function
This way the sort ensures that nested struct equality functions can
refer to previously introduced equality functions.

Make SimplifyLoopConditions testable
Add ShCompileOptions::simplifyLoopConditions, so that tests can turn
it on. Later edits to simplify loop condition logic are simpler to
review when the testing related edits are landed separately.
Test the feature by having ESSL as the input and ESSL as the natural
output, to reflect how AST changes.
To make the test expectations more deterministic across code changes,
change SymbolTable::kLastBuiltInId to
SymbolTable::kFirstUserDefinedSymbolId. This is simpler as no code
needs to know exact last built in id, so we can just ensure that
the user defined symbol ids do not clash with the builtin ids.

Fix for float constant precision in the GLSL backend.
Increase the precision of floating point values written out
via std::ostringstream. 8 digits is not sufficient to represent
all floating point values.
Note: the reason the locale test was modified is because it was using
a value of 1.9, which has no exact fp32 representation. Increasing
the precision causes it to print as 1.8999998 instead of 1.9, failing
the test. I've adjusted the value to 1.5, since this does have an
exact fp32 representation. (However, note that I couldn't get the test
to fail when I removed the locale setting, with either 1.9 or 1.5.
Perhaps the locale is being handled at a different level.)

WGSL: Output default uniform block and accesses to it
Default uniforms are put into a WGSL struct, and all accesses
of those uniforms now output struct accesses.
Similarly to I/O vars and builtins, these are outputted in a
pre-pass, but in the future it might make sense to do what
Vulkan does and do an AST transformation to put the default
uniforms into a UBO which should be outputted similarly.
This does not handle bool, matCx2, or array of element size < 16.

WGPU: Implement SetUniform() enough so GetUniform() works
Lays out a shadow buffer for basic uniforms per-shadertype
in std140, which is close to matching WGPU's layout. This
does not actually pass the buffer to WGPU as a uniform
buffer. GetUniform() just reads from the shadow buffer.
This is copied from the VK backend and so some code is
deduplicated.

WGSL: Rewrite input/output variables
GLSL builtin variables and in/out variables correspond to WGSL's main
function params and return value, so rewrite them accordingly.
This is done by generating structs to use as main function params and
return values, generating similar global structs, and copying the
former into the latter so the rest of the program can just use the
variables stored in the global structs.

ESSL -> WGSL: unary and binary exprs, operators, array access
Array indexing is always checked to be within bounds. For runtime-sized
arrays, this requires emitting a clamp(). For now this includes a bug
the left-side-expression (the array itself) has any side effects, which
shouldn't actually be possible but may be in future versions of WGSL.
Implementing unary, binary, and remaining aggregate expressions requires
implementing operators, many of which do not have exact corresponding
versions between GLSL and WGSL. This implements many operators but for
simplicity leaves some unimplemented and some half-implemented.
See WGSLOutput_test.cpp for some code examples.

ESSL -> WGSL: Emit func calls, struct access, constants
Also includes constructor calls, swizzles, and a slightly incorrect
version of the ternary operator.
The ternary operator doesn't exist in WGSL, only a non-short-circuiting
select() builtin. For now the ternary is implemented with select()
but that isn't correct if any of the true/false expressions have side
effects, and may have perf implications by computing both true/false
expressions.
Constants are mostly done after this, however NaN and infinity are not
valid constants in WGSL and it's unclear what we can do about this as
WGPU implementations are allowed to assume NaNs and infinities are
never operated on.

Vulkan: Use OpSelect with all types with SPIR-V 1.4
SPIR-V 1.4 relaxes the types that can be used as arguments of OpSelect.
Previously, the types were limited to scalars and vectors, but since
SPIR-V 1.4, it's unrestricted.
Writing tests for this change, another bug was discovered where support
for structs and arrays with the ternary operator was disabled due to
ESSL 1.0, even though that support is mandatory in ESSL 3.2.

Always redeclare clip/cull distance built-ins
When clip or cull distance built-in arrays are implicitly
sized, various pruning passes may produce an inconsistent
AST state thus causing translation or linking failures.
Adjusted the dedicated validation pass to inject
an explicit declaration thus bypassing the issue.
Additional updates:
* Ensured that API clip distance state emulation is
applied when a variable is declared but not assigned
* Reverted previous clip/cull distance related changes to
TIntermBinary::hasSideEffects as they are redundant now
* Fixed failing AST validation for MSL varying emulation
* Aligned linking error messages with the specifications
* Updated tests and cleaned-up obsolete code

Rewrite exprs using separated decl variables
Rewrite expressions that use the rewritten struct declaration variables.
Declaration that specfies a struct and defines multiple variables will
get its variable declarations separated. The type of the variable
changes when a struct specifier is removed for the second and rest of
the variable declarations. The type of the variable changes also when a
anonymous struct is named.
The expressions that used the separated variables used the old struct as
their types.
Fix by using TIntermRebuild. Upon creating a new symbol node referencing
the new type, the rebuilder will instantiate also all the needed
intermediate nodes, which then get the correct struct type.
For consistency, fix the case of anonymous struct -> named struct
transform naming the variables similar to named struct separation.
Consider base case:
struct S { .. } a, b; -> struct S { .. } a; S b;
Compare against case:
struct { .. } a, b;
Before, inconsistency:
struct s1 { .. }; s1 a; s1 b;
After, fixed:
struct s1 { .. } a; s1 b;

Metal: Generate names for rewritten inputs
When expanding multi-component fields to multiple single-component
fields, use AngleInternal namespace for the new names. The names are
generated with form "someField_0" where _0 is the component index.
If these are not created in AngleInternal, caller is able to create
a name clash by introducing single-component field "someField_0".
Fixes an assert where the vec4(a_) + vec4(a) would assert on size
mismatch because the variable lookup for "a_" would find a rewritten
variable for the expanded matrix row of "a".

Make appendDecimal use the last char of the buffer
ImmutableStringBuilder(1) means 1 char usable payload and \0.
This this should fit appendDecimal(1) but did not. Fix the off by one
error calling snprintf.
Also:
* removes const & from uint32_t argument
* removes const & from operator<<, to stay consistent
* Removes a redundant static_cast
* Implements operator<< const char* with potentially better
operator<<(const ImmutableString&) (may get compile time strlen)

Fix layout(index=) parse assert on es 100 shaders
Remove invalid assert about layout index qualifier being present only if
EXT_blend_func_extended is present.
The layout qualifier gets parsed to support EXT_shader_framebuffer_fetch
in ES 100 shaders to support
"layout(incoherent) mediump vec4 gl_FragData[gl_MaxDrawBuffers]"

Metal: Fix validation for anonymous struct arrays
Fix validation failure for accessing an element of
array of anonymous struct.
SeparateCompoundStructDeclarations would create
new Structures to name unnamed structures.
The Structure instance of the array index accessor
node was incorrect, it was the old Structure.
Use same pattern as in
SeparateStructFromUniformDeclarations.

Metal: Crash if for loop body is optimized away
Loops might have their bodies optimized away.
For case like `for(;;) if(false);` the constant pruning happens at
parse phase. The else branch (e.e. no else branch, nullptr) would be
selected as the body.
Some code treated the body as optional, some code treated it as
required. Define it as required, and remove all conditional code
related to the loop body.

Translator: Limit private variable size to 64KB
This is indirectly fixing an issue where passing large arrays in SPIR-V
such that an internal cast is needed (such as array inside interface
block copied to local varaible) causes an overflow of the instruction
length limit (in the absence of OpCopyLogical).
By limiting the size of private variables to 32KB, this limitation is
indirectly enforced. It was observed that all the test shaders added in
this CL fail on the Nvidia OpenGL drivers, so such a limit seems to be
reasonble.

Vulkan: Fix __samplerExternal2DY2YEXTtnd combined with swizzle
Pixel camera app is hitting assertion due to swizzle applied to swizzle.
This CL adds ReswizzleYUVOpsTraverser::visitSwizzle() method and detects
there is a swizzle on YUV sampler and apply YUV swizzle first and then
original swizzle and then fold two swizzle into one.
This CL added a test to reproduce the bug.
This CL also makes ShCompileOptions in ShaderExtensionTest class a class
member instead of local variable so that subclass can modify for testing
or debugging purpose.

Do not flush normal float constants to zero.
It's ok to flush denormalized constants to zero.
It's not ok to flush perfectly valid normal float constants >= FLT_MIN
to zero.
Two problems:
1) Values when parsed as doubles with a value less than FLT_MIN are
being flushed to zero. This is incorrect when the comparison is done
in double, since some values below FLT_MIN in double are equal to
FLT_MIN when cast to float. The fix is to perform the comparison in
float.
2) Values with a decimal exponent less than FLT_MIN_10_EXP are being
flushed to zero. FLT_MIN_10_EXP is -37 but FLT_MIN is 1.1754943E-38.
10^-37 may be the "minimum negative integer such that 10 raised to
that power is a normalized float", but being constrained to powers of
ten it's above FLT_MIN (which is 2^-126). Since this comparison is
done before #1 above, it's only present (AFAIK) to ensure that the
exponent will not make the pow() function overflow. Comparing against
-38 (FLT_MIN_10_EXP - 1) instead will do the trick.
