They cause a warning (-Wextra-semi) that can lead to a compile error
(-Werror).

Handle all basic scalar types in promoteConstantUnion

Add a bunch of missing cases to promoteConstantUnion. Use macros to expand all the cases more simply.

BUILD.gn: Fix file for use with Fuchsia platform build.

In order to upgrade the version of glslang used by the
Fuchsia platform source tree, BUILD.gn needs to be
slightly modified to care about the case where it is
not used with the Chromium //build configuration:

- Remove a new compiler warning to ensure proper
  compilation with -Werror (which is the default).

- Add a build target for spirv-remap, which is used
  by Fuchsia at build time to optimize the precompiled
  shaders of some of its graphics libraries.

AST/SPV: Fix #930: translate uvec4 <-> uint64 for SubgroupGeMask et. al.

On reading built-in variables SubgroupEqMask, SubgroupGeMask, SubgroupGtMask,
SubgroupLeMask, and SubgroupLtMask, the AST expects 64-bit ints, while SPIR-V
is defined as vectors of 32-bit ints.

The declaration type has to be translated in the opposite direction.

SPV: Add a switch for favoring non-NaN operands in min, max, and clamp.

Add Float16/Int8/Int16 capabilities for private variables and function parameters

Fix gl_SubGroupSizeARB builtin treatment

Add gl_SemanticsVolatile to GL_KHR_memory_scope_semantics, and make volatile-qualified atomics generate MemorySemanticsVolatile when using the Vulkan memory model

When processing Geometry and Tessellation Control/Evaluation shaders,
the builtins defined by GL_ARB_shader_ballot were not processed by
glslang. This specially a problem for gl_SubGroupSizeARB because, it is
treated as shader input instead of uniform on Vulkan.

Update tools

Support GL_NV_shader_sm_builtins

Including spirv and AST tests

Also increase size of TBuiltInVariable bitfields since we've now exceeded 127
and add a static_assert to make this easier to find next time it happens!

Use spvValidatorOptionsSetBeforeHlslLegalization for pre-legalized HLSL

Uppdate spirv-tools known-good

Remove unused parameter

Add missing NV_EXTENSIONS ifdef

Support GL_ARB_fragment_shader_interlock

Remove glslang.y from gn sources

Fix subgroup support for ray tracing

Closes #1735

GlslangToSpv.cpp
- minor formatting cleanup

BaseTypes.h
- minor formatting cleanup
- add subgroup builtins to GetBuiltInVariableString
  (was resulting in "unknown built-in variable" messages in test output)

Initialize.cpp
- better naming and re-use of strings for subgroup builtin variable declarations
- define subgroup builtin variables in ray-tracing shaders

intermOut.cpp
- add handling of the EOpSubgroupParition* variables
  (was resulting in "ERROR: Bad aggregation op" messages in test output)

Update test results.

with subgroup touch tests (error and non-error cases)
Currently the subgroup built-ins are NOT giving the correct output.
This is fixed in the next commit.
