(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.
