7213324259 Reframe the preprocessor as a C++ class, with instances, removing all C code, removing all global variables. Upgrade bison version to pass a parse context on through to the preprocessor. All the basic things to make something thread safe.

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

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.

06f8464fb5 Create linkage symbol nodes in the AST so a linker has access to all global objects that were declared, for error checking, etc. Use it now for all ins/outs/uniforms as well as gl_VertexID and gl_InstanceID.
Also fixed a confusing name and added more 'const'.
