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

73ed17a87b Rationalize naming/access to current thread-local-storage scheme. However, the preprocessor tokenizer is not thread-safe, so this may all change.
Also adding missing test.

1fde51d3fb 1) Don't propagate precision of built-in function arguments to return type when return type is bool (e.g., isnan).
2) Check an additional path for missing default precision qualification, except allow built-in declarations to pass the check.
