LoopDawg 0fca0bafaf WIP: HLSL: support global const initializers from non-constant rvalues
Semantic test left over from other source languages is removed, since this is permitted by HLSL.
Also, to support the functionality, a targeted test is performed for this case and it is
turned into a EvqGlobal qualifier to create an AST initialization segment when needed.

Constness is now propagated up aggregate chains during initializer construction.  This
handles hierarchical cases such as the distinction between:

    static const float2 a[2] = { { 1, 2 }, { 3, 4} };

vs

    static const float2 a[2] = { { 1, 2 }, { cbuffer_member, 4} };

The first of which can use a first class constant initalization, and the second cannot.

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.
