LoopDawg e2713125b9 HLSL: fix several issues in mat construction from scalars
This fixes:

1. A compilation error when assigning scalars to matricies

2. A semantic error in matrix construction from scalars.  This was
initializing the diagonal, where HLSL semantics require the scalar be
replicated to every matrix element.

3. Functions accepting mats can be called with scalars, which will
be shape-converted to the matrix type.  This was previously failing
to match the function signature.

NOTE: this does not yet handle complex scalars (a function call,
say) used to construct matricies.  That'll be added when the
node replicator service is available.  For now, there's an assert.

There's one new test (hlsl.scalar2matrix.frag).  An existing test
lsl.type.half.frag changes, because of (2) above, and a negative
test error message changes due to (3) above.

Fixes #923.

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.
