This change strips a few features similar to GLSLANG_WEB but doesn't
remove every detail like the latter. It also hardcodes profile/version
to core/450.
In particular, TBuiltIns::initialize is specialized to remove most of
what is not supported or won't be supported by ANGLE. The result of
this function is parsed with TParseContext::parseShaderStrings which is
a performance bottleneck.
This change shaves about 300KB off of ANGLE's binary size and reduces
the cost of SetupBuiltinSymbolTable to nearly a sixth.

* Introduces builtin variables gl_SecondaryFragColorEXT and gl_SecondaryFragDataEXT
* Introduces builtin constant gl_MaxDualSourceDrawBuffersEXT
* enables support for layout qualifier "index" in es profile
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.
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.
According to the 32-bit counterparts, their forms should be
genI64Type findLSB(genI64Type value)
genI64Type findLSB(genU64Type value)
genI64Type findMSB(genI64Type value)
genI64Type findMSB(genU64Type value)
