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.
(and GL_NV_shader_subgroup_partitioned) based on GL/ES version
instead of predicating it on vulkan SPV generation
Also add AST testing.
The glsl.450.subgroup* files are largely the same as the spv.subgroup*
The glsl.es320.subgroup* files are the same as the 450 versions, but modified to be ES compatible.
