765cee8441 GLSL/SPV: Pre SPIR-V 1.5, subgroupQuadBroadcast index must be constant 2019-10-14 23:08:26 -06:00

2cb2f197a7 Add support for 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!

51760c88ca Add more subgroup testing 
Touch test all subgroup builtins in vert, tesc, tese, geom, frag, compute shaders
before and after enabling extensions to make sure the correct errors are generated
and then not generated (after enablement).

83170e3f7a Enable GL_KHR_shader_subgroup properly 
(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.
