93dfbe1309 glslang: Fix over 100 warnings from MSVC warning level 4. 
git-svn-id: https://cvs.khronos.org/svn/repos/ogl/trunk/ecosystem/public/sdk/tools/glslang@31202 e7fa87d3-cd2b-0410-9028-fcbf551c1848

ac1e188f3b GL_ARB_enhanced_layouts, part 6: Numerical side of uniform offset and align semantics. Included 
- moving offset calculations for std140/std430 from reflection to linkValidate.cpp
 - applying the offset/align rules on top of std140/std430
 - removing caching the structure's number of components (and correcting that this is components, not size)

a9819921b3 Improvement to the AST traversal infrastructure. 
Note:  This affects any downstream consumers of glslang's traverser.  Let me know if there are any issues.  Essentially, you will need to change the functions that were pointed to into overriding base-class members instead.  See the examples in this check in.

0876a58203 Misc. constant-folding fixes: Check % for 0, mat(mat) constructor, index range checking (within constant objects). Also, rationalize addConst*() methods.

27b72e42c3 Implement ES 2.0 (version 100) limitations for non-inductive loop detection and array indexes needing "constant-index-expressions" (inductive variables and constant expressions).

f2ee3dd46a Add full support for uniforms with initializers, including intra-stage link validation of aggregate constant initializers. 
This included 
 - encapsulating aggregate constants
 - removal of constant-aggregate comparison algorithms, instead using a flattened and direct std::vector comparison
 - adding structure type comparison for independently declared structures that still might match types

807b8e3b82 Remove TIntermediate's dependency on infoSink, simplify folding of constant aggregates, and infoSink use in constant folding. 
Added a few deep aggregate constant folding testing cases.

5f1a0b7998 Eliminate flex as the GLSL lexical analyzer, going from two nested lexical analyzers down to one, leaving just the preprocessor's lexical analysis. A new layer replaces it, to translate from the preprocessor's view of tokenization to glslang's view of tokenization. 
Also:
 - change source locations from an int to TSourceLoc (shader number, line number) throughout
 - various improvements to the preprocessor

ba04210097 Add anonymous members as a new symbol table type, so the infrastructure can handle blocks with no names. 
Also, add more safety to the types involved regarding copy constructors, operator=, etc.

f0fdc53e2a Implement non-square matrices, and make a few type improvements. Cleaned up a few old issues. Added two tests. 
Details
 - added all the new non-square types
 - separated concepts of matrix size and vector size
 - removed VS 6.0 comments/workarounds
 - removed obsolete concept of matrix fields
