Remove repeated "success" check from compileTreeImpl
This refactoring simplifies the compilation code by putting AST checks
and simplification into a separate function. This function will
immediately return false when an error is encountered. This is easier
to maintain than repeated checking of a "success" boolean.

Remove empty switch statements from translated shaders
The native HLSL compiler does not accept switch statements with an
empty statement list. The simplest way to accommodate this is to
simply remove them from the AST after parsing and some initial
pruning.
This is done by the new RemoveEmptySwitchStatements traverser. It
preserves init statements of switch statements in case they have side
effects. So for example
switch(++i) {}
gets translated to
++i;

Prune no-op statements with a single traverser
We put pruning literal statements and pruning empty declarations in
the same traverser, as some of the required logic is the same. This
pruning of no-ops is always done as one of the first processing steps
after parsing, so further processing of the AST is simpler.
Since we now prune pure literals before removing no-op cases from the
end of switch statements, we also don't need any sort of special
handling for switch statements in pruning pure literals.

Generate performance warnings in HLSL translation
Generate performance warnings for some code that undergoes heavy
emulation when translated to HLSL:
1. Dynamic indexing of vectors and matrices.
2. Non-empty fall-through cases in switch/case.
The warnings are generated only when code is translated to HLSL.
Generating them in the parsing stage would add too much maintenance
burden.
Improves switch statement fall-through handling in cases where an
empty fall-through case follows a non-empty one so that extra
performance warnings are not generated.

Fix switch statement validation corner cases
The grammar needs to generate AST nodes even for no-op statements,
since they might be the last statement in a switch statement that is
required for switch statement validity. Change the grammar to generate
nodes from empty blocks and empty declarations.
We also need to do some further processing of the AST. This is because
PruneEmptyDeclarations will still remove empty declarations, and at
least the NVIDIA driver GLSL compiler doesn't accept some types of
no-op statements as the last statement inside a switch statement. So
after parsing has finished we do rudimentary dead code elimination to
remove dead cases from the end of switch statements.

ES31: Enable 'location' layout qualifier on shader interfaces in compiler
This patch enables 'location' layout qualifier for vertex outputs and
fragment shader inputs when the shader version is 3.1 in ANGLE GLSL
compiler and adds the check on location conflicts for these varyings.
According to GLSL ES 3.1 SPEC (Chapter 4.4.1 and Chapter 4.4.2),
'location' layout qualifier is allowed on both inputs and outputs of
vertex and fragment shaders.
'location' layout qualifier on shader interfaces is only valid on shaders
whose version is 3.1 and above. According to GLSL ES 3.0 SPEC, vertex shader
cannot have output layout qualifiers (Chapter 4.3.8.2) and fragment shader
cannot have input layout qualifiers (Chapter 4.3.8.1).
The 'location' qualifier on varyings is used in the shader interface
matching defined in OpenGL ES 3.1. (OpenGL ES 3.1 SPEC Chapter 7.4.1). This
new link rule will be added to Program.cpp in another patch.
For the OpenGL ES 3.1 extension GL_OES_geometry_shader, according to
GL_OES_shader_io_blocks SPEC (Chapter 4.4.1 and Chapter 4.4.2), 'location'
layout qualifier is both valid on geometry shader inputs and outputs. This
feature will be implemented together with other rules on geometry shader
inputs and outputs.

Allow length() on arbitrary array expressions
This is required to pass some dEQP GLES 3.1 tests for arrays of
arrays, and WebGL conformance tests were also recently fixed to
require this behavior. The intent of the GLSL ES spec was not to
restrict usage of length().
In practice GL drivers don't implement array length() on expressions
with side effects correctly in all cases. HLSL doesn't have an array
length operator either. Because of this we always remove array length
ops from the AST before output.

Only support GL_OVR_multiview extension variant
The WebGL spec proposal was changed so that only GL_OVR_multiview
extension name is supported, instead of having two variants
OVR_multiview and OVR_multiview2. We're only supporting the WebGL
version of the shader extension, so we drop compiler support for
GL_OVR_multiview2. Shader restrictions were also removed from the
WebGL spec, so no special validation for how ViewID_OVR gets used is
needed.
Tests that were testing for the shader restrictions are either removed
or changed from negative tests to positive tests.

Clamp point size to maximum point size from the API on NVIDIA
NVIDIA OpenGL drivers have a bug where the point size range is being
reported incorrectly - it appears the core GL driver incorrectly gives
the range for smooth points, when it should be giving the range for
aliased points. Clamp the actual point size to the maximum point size
reported from the API so that the GLES spec is followed.
The same workaround seems to be necessary also on Android. The issue
was revealed by the trybots, and has not been fully diagnosed though.
The newly added test fails on AMD OpenGL.
As a part of this change, the existing tests in PointSpritesTest are
refactored to use gl_raii.

TIntermTraverser as it is not related to the core functionality
of traversing and transforming ASTs.

- Intermediate output is now in OutputTree.h/.cpp
- Max tree depth check is now in IsASTDepthBelowLimit.h/.cpp

Set proper symbol ids on temporary symbol nodes
Temporary symbols used to all have symbol id 0. Now they get assigned
unique symbol ids. This makes it possible to keep track of them
according to the symbol id instead of their name, paving way to more

Clean up redundant initialization of gl_Position
In case gl_Position is statically used in the input shader, setting
the INIT_OUTPUT_VARIABLES flag will initialize gl_Position. Avoid
redundant initialization of gl_Position in this case.
Includes cleaning up memory management in InitOutputVariables_test:
all the pool-allocated variables will be freed at the end of each test
when the memory pool is cleared, so manual memory management is not
needed.
Also includes making the zero node check used in unit tests stricter
so that the tests are more reliable and moving it to
ShaderCompileTreeTest.h so that it can be reused in the future.

Propagate correct type to the lvalue in an output variable initializer
With the SH_INIT_OUTPUT_VARIABLES option enabled, vertex and fragment
shader outputs get initialized with zeros at the beginning of main.
However, previous to this patch the lvalues in the binary expression did
not receive the correct type. This can lead to incorrect modifications
of the AST in subsequent stages or incorrect output code from the
translator. The patch addresses the issue by copying the type
information from the symbol table.

Remove most of the remaining logic from glslang.y
Move most of the logic in glslang.y to ParseContext. This will make it
easier to change the code in the future.
Only a few specific bits of logic are kept in glslang.y:
* Disabling a parsing rule when a given shading language version is
being parsed. This makes it easier to check the grammar against the
grammar in the GLSL ES specs.
* Scoping calls that need to be paired with another call. It's much
easier to check these for correctness when the paired calls are next
to each other.

Initialize uninitialized globals in GLSL output
Initializing globals is done by the DeferGlobalInitializers AST
transformation, which makes sure that the global variable init
proceeds in the correct order. This is important since some global
variables may use other uninitialized globals in their initializers.
The global variable init is only done in case the WebGL shader spec is
being followed. This avoids adding global initializers twice in case
the same shader goes through multiple translations, assuming only one
of them is a WebGL shader translation.

Initialize uninitialized locals in GLSL output
Guarantee that local variables are initialized before they are used
in GLSL output. In HLSL output all variables were already being
initialized.
Locals are initialized using an AST transform. The local variable init
can only be run after some simplification of the AST, so that it is
able to handle complex cases like:
for (int i[2], j = i[0]; i[0] < 3; ++i[0]) {
}
If we're dealing with ESSL 1.00 which lacks array constructors, in
this kind of case the uninitialized array initialization code needs to
be hoisted out of the loop init statement, and the code also needs to
make sure that j's initializer is run after i is initialized.
Another complex case involves nameless structs. This can be an issue
also in ESSL 3.00 and above:
for (struct { float f; } s; s.f < 1.0; ++s.f) {
}
Since the struct doesn't have a name, its constructor can not be used.
We solve this by initializing the struct members individually,
similarly to how arrays are initialized in ESSL 1.00.
Initializing local variables is disabled on Mac and Android for now.
On Mac, invalid behavior was exposed in the WebGL 2.0 tests when
enabling it. On Android, the dEQP test runs failed for an unknown
reason. Bugs have been opened to resolve these issues later.

The failure is due to when we initialize variables to 0, we re-create
the struct TType, and it contains a different unique id from the
original struct TType, thus leading to a different hashed name.

Remove invariant declaration in vertex shader for translation from ESSL 3.00 to GLSL <= 4.1
This is a follow-up patch of
https://chromium-review.googlesource.com/408569. This CL removes
invariant declaration in ESSL 3.00 vertex shader, such like:
"
out vec4 foo;
invariant foo;
"
This CL also adds the workarounds in libANGLE.

translator: Put ShaderLang APIs in "sh" namespace.
Working with glslang in Vulkan means we are static linking libANGLE
with functions that have the same name as our translator APIs. We
can fix this by scoping our APIs. We don't need to scope the types
of the file, since they don't conflict.
This will require a follow-up patch to remove the unscoped APIs
once we switch over Chromium.
We also scope TCompiler and some related classes to avoid multiply
defined link errors with glslang.

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 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.

Reland "Add workaround for unused std140 and shared uniform blocks on MacOS"
On some Mac drivers with shader version 4.1, they will
treat unused std140 and shared uniform blocks' members as inactive. However,
WebGL2.0 based on OpenGL ES3.0.4 requires all members of a named uniform block
declared with a shared or std140 layout qualifier to be considered active.
The uniform block itself is also considered active.
This workaround is to reference all members of unused std140 and shared uniform blocks
at the beginning of the vertex/fragment shader's main().

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.

Remove SH_TIMING_RESTRICTIONS compiler flag
The timing restrictions code is not in use and not updated for ESSL3,
so it is better to remove it to make refactoring the AST easier.
It can also be argued that perfect prevention of shader timing attacks
is not feasible due to factors that are not under control of ANGLE,
such as fixed function color compression in GPUs. Such color
compression may make the use of texture bandwidth and thus performance
dependent on the content of a texture regardless of whether a
compressed format is chosen through the API.
SH_DEPENDENCY_GRAPH flag that could only be active together with the
timing restrictions flag is also removed, along with all the code that
was supporting it. The newer CallDAG code is used for different
purposes and is kept.

Clean up unary and aggregate math folding
Prefer asserts instead of adding internal errors to the compiler log
when types of arguments are not as expected or the folding function
runs into an operation it can't handle. Neither of these cases should
be possible, the checks for correct argument types are solid at this
point.
In the future, when new built-in functions are added, constant folding
support for them should be added as well.
foldUnaryWithDifferentReturnType and foldUnaryWithSameReturnType are
renamed to foldUnaryNonComponentWise and foldUnaryComponentWise
respectively. These names better reflect what these functions are
doing.
The info sink member is removed from TIntermediate, since TDiagnostics
is now passed into the functions that may generate warnings instead.

Add compute shader compilation support in the glsl compiler
Support is added for compute shader compilation. There is a small
extension to the parser so that 'local_size_x = ', 'local_size_y = '
and 'local_size_z = ' are supported as layout qualifiers.
A few shader compilation tests are added and one which checks the AST
whether the layout qualifiers are properly parsed.

Fix output variable gl_FragData array size issue.
If the GL_EXT_draw_buffers extension isn't explicitly enabled in the shader,
then gl_FragData is an array of size 1, not of size max_draw_buffers.

Fix member variable masking warning in standalone MSVS build
The patch for initializing output variables introduced a warning that
broke MSVS 2015 standalone build. The "shaderType" variable passed to
TCompiler::initializeOutputVariables was unnecessary and had the same
name as a member variable of TCompiler that stores the shader type.

Add support for ES31 context creation
The dEQP test for context creation passes.
SH_WEBGL3_SPEC has been added, but it should be considered whether we
should keep it, remove it or rename it. It was added so that there is
a webgl mapping to es 310 shaders. Check Compiler.cpp. The bison file
has been modified so that some tokens from es3 can be also used in
es31 as well.
A separate macro ES3_1_ONLY is added so that some tokens are limited
only for es 310 shaders.
