Support pixel local storage on ES 3.0
Now that the application-facing API is implemented, we don't have to
rely on ES 3.1 anymore. Expose and test the extension on ES 3.0.

Translator: Clean up the compile flag passing interface
Historically, compile flags were sent to the translator as a bitmask.
Recently, we were getting close to running out of bits.  Additionally,
direct-to-metal work had started to introduce constants to be passed to
the translator, which were misplaced in ShBuiltInResources and Caps.
Recent work on Pixel Local Storage adds even more constants, aggravating
the situation.
In this change, the interface to passing compile flags is reworked.  A
struct is passed (instead of a bitmask) that has one bit for each flag.
This can be indefinitely extended.  Additionally, the constants needed
by metal and PLS are also placed in this struct.  In turn, the backends
can set these options directly, and don't have to hack them into Caps to
further get hacked into ShBuiltInResources.

Translator: Generate Ops for all built-in functions
EOpCallBuiltInFunction is removed in this change, as well as the
"op": "auto" property in builtin_function_declarations.txt.  Instead,
gen_builtin_symbols.py automatically generates Ops for every built-in
function and generates the TOperator enum accordingly.
This simplifies SPIR-V code generation by allowing switches to be used
on operators instead of string comparisons.

Declare specialization constants in the AST
A new qualifier (EvqSpecConst) is added so that specialization constants
can be declared in tree.
This enables TVariable references to specialization constants to be
validated, which were in fact invalid as every reference declared a new
variable.  That is fixed.

Translator: Allow invariant on I/O block members
The GLSL ES 3.2 spec says:
> Only variables output from a shader can be candidates for invariance.
And:
> All uses of invariant must be at global scope or on block members, and
> before any use of the variables being declared as invariant.
As a result, it's possible to specify `invariant` on a member of an
output I/O block.

Translator: Ensure structs and blocks are uniquely defined
A new AST validation is added to ensure that the same TStructure or
TInterfaceBlock is not redundantly defined.  This helps with SPIR-V
generation by allowing the id to be used as key in a hash map that looks
up the corresponding SPIR-V type id.
A bug is fixed where the Vulkan driver uniform declaration created two
identical declarations for ANGLEDepthRangeParams.
A number of other bugs are also fixed in this change, where if a
variable declaration is eliminated (for example due to constant folding,
or inactive interface variable removal) and it contained a struct
specifier, the struct declaration was also removed.  OutputGLSLBase had
a hack where structs were declared on first encounter, which was
incorrect as the scope of the declaration could change.  Those bugs are
fixed and this hack is removed.

Vulkan: Set varying location & xfb decorations in SPIR-V
The shader translator outputs arbitrary location indices.  Once compiled
by glslang, the SPIR-V transformer modifies these decorations.  If the
transform feedback extension is used, it will also add the relevant
decorations to the varyings that are captured.

Vulkan: Remove row->col major shader transformation
This was done based on the incorrect assumption that Vulkan GLSL doesn't
allow layout qualifiers on interface block fields.  This was due to
glslang compile failures in some shaders that included mixed row- and
column-major fields in interface blocks.
However, the failures were only in the case the interface block is
inactive, in which case glslang wrapper previously replaced the
layout/qualifier of the interface block with |struct|, which left the
shader with an unused struct definition with fields that have layout
qualifiers; an invalid shader.
The change introduced in
https://chromium-review.googlesource.com/c/angle/angle/+/1951523
removes inactive shader interface declarations.  The above scenario thus
never occurs, rendering the row- to column-major transformation
unnecessary.

Translator: Memory qualifiers on SSBO fields
These were not output prior to this CL.  Of these qualifiers, readonly
and writeonly are unnecessary as ANGLE already does the appropriate
validation, but the rest (coherent, volatile, restrict) are necessary,
even though the tests pass on the bots by coincidence of driver
behavior/test simplicity.

Implement SamplerVideoWEBGL for WEBGL_video_texture extension on desktop
WEBGL_video_texture is an extension that will improve uploading video frame to WebGL performance.
(https://www.khronos.org/registry/webgl/extensions/proposals/WEBGL_video_texture/)
This extension introduced a new texture type TEXTURE_VIDEO_IMAGE_WEBGL and a new sampler type
samplerVideoWEBGL to sample it.
In chromium implementation, TEXTURE_VIDEO_IMAGE_WEBGL maps to different native texture type
based on platform. On desktop, it maps to GL_TEXTURE2D(Currently supported). On Android, it
should map to GL_TEXTURE_EXTERNAL(TODO). SamplerVideoWEBGL needs to be mapped to sampler2D or
samplerExternalOES according to TEXTURE_VIDEO_IMAGE_WEBGL implementation.
This patch implements samplerVideoWEBGL in Angle to support WEBGL_video_texture on desktop. In
this case, samplerVideoWEBGL should map to sampler2D.

Vulkan: Have the translator output in/out qualifiers
Currently, when assigning varying locations, we assign in/out qualifiers
based on whether the varying name is present between different shader
stages.
This is broken for separate shader objects as there is possibly no pair
of shaders to be able to tell which is input and which is output (by
trying to find the same varying in a stage before or after the shader).

Don't use TIntermSymbol nodes for function parameters
Parameter nodes are not needed - it's simpler to just create a
TVariable object for each parameter when the TFunction is initialized.
With this change we also store only one object per each parameter type
used in built-in functions, instead of one array of TConstParameter
entries for each unique parameter sequence.
This simplifies code and reduces binary size and compiler memory use.
Compiler perf does not seem to be significantly affected.

Most of the code that deals with names is changed to use
ImmutableString where it makes sense to avoid conversions.
The lexer/parser now allocate const char pointers into pool memory
instead of allocating TStrings. These are then converted to
ImmutableString upon entering TParseContext.

Replace remaining usage of TName with TSymbol
TName used to contain just a subset of the information stored in

converting it to TName.
This also improves type safety a bit by making some functions only
take in TVariable or TFunction instead of the more generic TName.

Vulkan: Support multiple vertex outputs.
This is a bit of a hack, similar to how D3D11 works. We need to write
output locations in the GLSL shader before we send them to glslang,
so we wait until the link call, then string-replace some hard-coded
identifeir code to the attribute location determined by ANGLE.
This CL also fills in some of the vertex format conversion tables in
formatutilsvk.cpp.

The Vulkan GLSL translator back-end will handle validating and

glslang (the Vulkan one) accepts both GLSL and GLSL ES shaders
as inputs, and both the desktop and ESSL back-ends give
incompleteness warnings when used. For now, use the desktop GL
450 as a target for Vulkan GLSL.
The Vulkan-specific changes are currently only to add locations
to every vertex input and fragment output.

This change is pure refactoring and doesn't fix bugs related to
invariant declarations. Invariant declarations are supposed to accept
a list of identifiers, but this refactoring keeps the current behavior
of only accepting a single identifier in an invariant declaration.
When the bug will be fixed, the new TIntermInvariantDeclaration class
that now has only a single child node can be changed so that it may
have multiple children.
TIntermAggregate is still used for function calls, function
prototypes and function parameter lists.

Output infinity and NaN literals correctly in shaders
Previously infinity and NaN resulting from constant folding would be
clamped to finite 32-bit float range when they were written in shader
output. Now they are written as a bit pattern in case the shader
version allows it.
This does not guarantee that NaNs work, but this is fine, since ESSL
3.00.6 spec has very loose requirements when it comes to NaNs.

translator: remove code related to for-loop unrolling

Also remove MMap.h which was unused.

Reland "Remove invariant qualifier for input in fragment shader"
This relands https://chromium-review.googlesource.com/#/c/400005/.
ESSL and GLSL are not consistent on invariant matching in vertex shader
and fragment shader. See the following rules:
ESSL 1.00 - input and output must match
ESSL 3.00 - only output, inputs cannot be declared as invariant.
GLSL 1.10.59 - does not exist
GLSL 1.20.8  - input and output must match
GLSL 1.30.10 - input and output must match
GLSL 1.40.8  - input and output must match
GLSL 1.50.11 - input and output must match
GLSL 3.30.6  - input and output must match
GLSL 4.00.9  - input and output must match
GLSL 4.10.6  - input and output must match
GLSL 4.20.11 - input can omit invariant
GLSL 4.30.8  - input can omit invariant
GLSL 4.40.9  - input can omit invariant
GLSL 4.50.5  - input can omit invariant
Since GLSL 4.20, invariant qualifier description were changed to:
"
Only variables output from a shader (including those that are then input
to a subsequent shader) can be candidates for invariance. This includes
user-defined output variables and the built-in output variables. As only
outputs need be declared with invariant, an output from one shader stage
will still match an input of a subsequent stage without the input being
declared as invariant.
"
It's not very clear if input in fragment can be declared as invariant.
Mesa driver disallows use of input declared as invariant in fragment
shader, while other drivers may allow it. This CL removes invariant
declaration for input in fragment shader except AMD driver in Linux.
AMD's driver obviously contradicts the spec by forcing invariance to
match between vertex and fragment shaders.

Split TIntermDeclaration from TIntermAggregate
The new class TIntermDeclaration is now used for struct, interface
block and variable declarations. TIntermDeclaration nodes do not have
a type - rather the type is stored in each child node. The types may
differ in case the declaration is a series of array declarators with
mismatching sizes.
TIntermAggregate is still used for function calls, function
prototypes, function parameter lists and invariant declarations.

Split TIntermFunctionDefinition from TIntermAggregate
This makes the code easier to understand. Function definition nodes
always have just two children, the parameters node and the function
body node, so there was no proper reason why they should be aggregate
nodes.
As a part of this change, intermediate output is modified to print
symbol table ids of functions so that debugging function id related
functionality will be easier in the future.
After this patch, TIntermAggregate is still used for function
prototypes, function parameter lists, function calls, variable and
invariant declarations and the comma (sequence) operator.

Split TIntermBlock from TIntermAggregate
The new TIntermBlock node class replaces TIntermAggregate nodes with
the EOpSequence op. It represents the root node of the tree which is
a list of declarations and function definitions, and any code blocks
that can be denoted by curly braces. These include function and loop
bodies, and if-else branches.
This change enables a bunch of more compile-time type checking, and
makes the AST code easier to understand and less error-prone.
The PostProcess step that used to be done to ensure that the root node
is TIntermAggregate is removed in favor of making sure that the root
node is a TIntermBlock in the glslang.y parsing code.
Intermediate output formatting is improved to print the EOpNull error
in a clearer way.
After this patch, TIntermAggregate is still used for function
definitions, function prototypes, function parameter lists, function
calls, variable and invariant declarations and the comma (sequence)
operator.

Split ternary node class from TIntermSelection
Ternary operator nodes are typed parts of expressions, they always
have two children and the children are also guaranteed to be
TIntermTyped. "If" selection nodes can't be a part of an expression,
they can have either one or two children and the children are code
blocks. Due to all of these differences it makes sense to store these
using two different AST node classes.

It's cleaner to mark internal functions by using the TName class,

Still missing from this version: HLSL output, array support in

Add an SH_GLSL_CORE_OUTPUT profile.
So we could generate shaders for Apple using core GL profile.
By switching to core profile, we still pass most WebGL conformance tests 1.0.2 on Linux, but not all, so apparently more work is needed.
However, I think it's OK to check this CL in because this output profile will be only used behind a chromium switch.
