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.

ebeeece6a7 Add uint type (big change). For both int/uint, add the operators >>, <<, &, |, and ^. Also added unsigned literals and uint precision support. Also fixed how int/uint literal underflow/overflow is handled.

4055816bc9 Add compilation mode flags for forward-compatible contexts and relaxed error checking. These initiate as arguments to ShCompile() and both default to being off.

53fb465729 Change infrastructure to support constant folding across built-in functions, as required by 1.2 semantics. Partially fleshed out with min/max and some trig functions. Still have to complete all operations.
