GLSL Version : >= 150
Purpose:
Allow users to use features by enabling this extension, even in low versions.
Extension Name:
ARB_gpu_shader_fp64
Builtin-variables:
Nah
Builtin-functions:
functions overloaded for this extension, please check registry in reference.
Keywords:
Double
Features:
add support for type "double"
Reference:
https://www.khronos.org/registry/OpenGL/extensions/ARB/ARB_gpu_shader_fp64.txt
Add support for implicit conversion
1. Remove builtin double vertex (this is introduced by vertex_attrib_64bit
2. Add extension check and implicit conversion as double has been introduced
3. Add test results.

TPoolAllocator is not copy assignable, so this setter could never have
been used. After a recent change (878a24ee2), new versions of Clang
reject this code outright.
v2: Move addCapability and addExtension extension calls from
TGlslangToSpvTraverser::createBinaryOperation to
TGlslangToSpvTraverser::visitAggregate. Suggested by JohnK.
The changes to glslang/glslang/MachineIndependent/ParseHelper.cpp exist
purely to prevent even more instances of "warning: enumeration value
‘EOp...’ not handled in switch"
v2: Remove 8-bit types. Overzealous copy-and-paste led to adding
support for a bunch of types that the extension doesn't actually enable.
v3: Update expected test results file. Just changing an expected
results file to make a test pass seems sketchy to me, but I'm not sure
what else to do.
v4: Add missing entry for EOpAbsDifference in
TOutputTraverser::visitBinary. Noticed by JohnK.
There is a flag to disable the SPVRemapper during the GLSLang build.
That flag is check in some, but not all spots so if you try to build
with SPVRemapper disabled you get CMake errors and compile errors.
This CL fixs up the build so building with -DENABLE_SPVREMAPPER=0 will
complete correclty.
The problem is that constructing a float16_t, int8_t, uint8_t, int16_t,
or uint16_t with a non 32-bit argument generates an aggregate with the
wrong construction op. For int8_t and uint8_t, this resulted in a crash.
The SPIR-V post-processing to discover capabilities and
extensions does not apply to WebGPU compilation. So don't include
that code.
This reclaims some of the code space added by #1943
