Translator: Remove SubpassInputMS
ANGLE never generates multisampled input attachments, because it cannot
know if the shader will be used with a single-sampled or multisampled
framebuffer.
The SPIR-V transformer takes care of changing the type and ops to be
multisampled if needed.

Implement OES_tessellation_shader
Based on the specs, there are no functional differences between
OES and EXT.
* Added validation for glPatchParameteriOES() and the core
glPatchParameteri().
* Added the extension support for GLSL.
* EXT_shader_io_blocks is implicitly enabled for the EXT geometry
and tessellation shader extensions.
* OES_shader_io_blocks is implicitly enabled for the OES versions
of said extensions.
* Added a test to make sure using this extension works instead of EXT.
* Turned the repeated test code into a function:
* testTessellationTextureBufferAccess
* Skipped the tests that fail on various platforms.
* It seems that these tests were being skipped before enabling
this extension ("Not supported").

Translator: Allow subpassLoad in AST in ESSL
subpassLoad is available to desktop GLSL, but not GLSL ES. With this
change, subpassLoad is made available internally to the AST so that
framebuffer fetch's use of this built-in can be simplified.
Additionally, this makes the tree more consistent in that there's no
function call without a corresponding function declaration.
A follow up change will add an AST validation to enforce this.

gen_builtin_symbols.py automatically generates Ops for every built-in

Translator: Enable geometry and tessellation in ES3.2
Symbols that these extensions introduced were only accepted if the
extension directive was present. This is not necessary for es 320
shaders. This change adds a new tag to builtin variable and function
declarations in the translator, namely "essl_extension_becomes_core_in"
which makes gen_builtin_symbols.py automatically create two entries for
the builtin; one with the specified level and extension, one with the
core level and without extension. Entries in
builtin_function_declarations.txt can potentially be deduplicated as a
follow up to take advantage of this tag, though likely an anologous
"glsl_extension_becomes_core_in" needs to be introduced.

GL: Support GL_OES_texture_cube_map_array in shader translator
GL_OES_texture_cube_map_array is core in 3.2. This CL adds support
for this extension in the shader translator.
Now passes dEQP.KHR_GLES31/core_texture_cube_map_array.*,
dEQP.GLES31/functional_fbo_color_texcubearray_*, and
dEQP.GLES31/functional_opaque_type_indexing*samplercubearray* with GL backend.

Add support for non-float mix
The non-float variations of the mix builtin were conditioned to desktop
GLSL, but they are present in ESSL 3.1+. This change also implements
constant folding of these builtins as exercised by dEQP.

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.

Use OES_texture_storage_multisample_2d_array
There's an OES extension for multisample texture arrays,
OES_texture_storage_multisample_2d_array. Change references from
ANGLE_texture_multisample_array to the native extension in the shader
compiler.
ANGLE still needs to have robust behavior for out-of-range texel
fetches that's not found in the original extension, but this does not
need to be spelled out in the extension spec.

ES31: Support atomic functions on D3D11 - Part I
This patch is the first one of the implementation of atomic
functions in D3D11.
There are mainly two differences in the usage of GLSL and HLSL
atomic functions:
1. All GLSL atomic functions have return values, which all
represent the original value of the shared or ssbo variable;
while all HLSL atomic functions don't, and the original value
can be stored in the last parameter of the function call.
2. For HLSL atomic functions, the last parameter that stores the
original value is optional except for InterlockedExchange and
InterlockedCompareExchange. Missing original_value in the call
of InterlockedExchange and InterlockedCompareExchange results
in a compile error from HLSL compiler.
To handle these differences, we plan to implement the translation
in two steps:
1. Support direct translations from GLSL atomic functions to HLSL
ones.
Direct translation can only handle the following two situations:
(1) The sentence is a GLSL atomic function call without requesting
a return value and it is not atomicExchange or atomicCompSwap:
e.g.
GLSL: atomicAdd(mem, value);
-> HLSL: InterlockedAdd(mem, value);
(2) The sentence is a simple assignment expression: its right is
a GLSL atomic function call and its left is a declared variable.
e.g.
GLSL: oldValue = atomicAdd(mem, value);
-> HLSL: InterlockedAdd(mem, value, oldValue);
2. Support atomic functions in the situations that don't support
direct translations.
We will modify the intermediate tree to make direct translation work
on all these situations.
e.g.
atomicExchange(mem, value);
-> int oldValue;
oldValue = atomicExchange(mem, value);
int oldValue = atomicAdd(mem, value);
-> int oldValue;
oldValue = atomicAdd(mem, value);
return atomicAdd(mem, value);
-> int temp;
temp = atomicAdd(mem, value);
return temp;
for (i = 0; i < atomicAdd(mem, value); ++i)
-> int temp;
temp = atomicAdd(mem, value);
for (i = 0; i < temp; ++i)
{
...
temp = atomicAdd(mem, value);
}
int result = isTrue ? atomicAdd(mem, value) : 0;
-> int result;
if (isTrue)
{
result = atomicAdd(mem, value);
}
else
{
result = 0;
}
This patch completes Step 1 which mainly focus on the translation
from GLSL atomic functions to HLSL ones.

Use function id to group functions in ParseContext
This way we can do numeric comparisons instead of string comparisons.
The effect on compiler perf test scores is fairly marginal, but
this reduces binary size by a few kilobytes, and there may be a larger
effect on shaders calling a lot of texture functions.

Statically allocate built-in function symbols
A script gen_builtin_symbols.py now generates code for initializing
built-in function symbols. The TFunction objects are initialized at
C++ compile time.
The source file used for the functions is in a format that's similar
to how functions are given out in the GLSL spec, so it is easy to
maintain.
The function symbols are still inserted to the symbol table levels
same as before. Getting rid of inserting the symbols at runtime is
intended to be done as follow-up.
This speeds up angle_unittests on Linux in release mode by a bit less
than half, and in debug mode by more than half.
