Arseny Kapoulkine 76dd399629 Fix interaction between GL_EXT_mesh_shader and GL_EXT_fragment_shading_rate
Before this change, using gl_MeshPrimitivesEXT in mesh shader would
unconditionally create gl_MeshPrimitivesEXT.gl_PrimitiveShadingRateEXT
field and add PrimitiveShadingRateKHR capability to the output SPIRV
file, which would subsequently trigger validation errors when creating
the shader module unless the application requested primitive shading
rate feature.

What should happen instead is that unless GL_EXT_fragment_shading_rate
extension is enabled, we should not allow using
gl_PrimitiveShadingRateEXT and should not emit the associated fields
into the output.

This change fixes this by using existing filterMember mechanism that is
already used in a few other cases like this, and adjusting the required
extension on the field member which will generate an error when
gl_PrimitiveShadingRateEXT is used without enabling the extension.

Glslang Tests based on the Google Test Framework

This directory contains Google Test based test fixture and test cases for glslang.

Apart from typical unit tests, necessary utility methods are added into the GlslangTests fixture to provide the ability to do file-based integration tests. Various *.FromFile.cpp files lists names of files containing input shader code in the Test/ directory. Utility methods will load the input shader source, compile them, and compare with the corresponding expected output in the Test/baseResults/ directory.

How to run the tests

Please make sure you have a copy of Google Test checked out under the External directory before building. After building, just run the ctest command or the gtests/glslangtests binary in your build directory.

The gtests/glslangtests binary also provides an --update-mode command line option, which, if supplied, will overwrite the golden files under the Test/baseResults/ directory with real output from that invocation. This serves as an easy way to update golden files.
