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

ceb0623823 Fix another problem with undefined macros needing to evaluate to 0 within a preprocessor expression, but not outside a preprocessor expression.

52ac67e913 Make the PP report an error on undefined macro in "#if ..." for ES profiles, unless relaxed error checking is requested. Still works as normal CPP on non-ES. 
Also, improved error reporting in general for the PP.

b51f62c573 Add the GL_ES macro for ES personalities, along with a general mechanism for adding preambles in front of shaders without effecting line numbers, etc.

5d3e2e35b6 Support suffixes for floats and doubles (none were supported in 110). 
Add preprocessor support for parsing doubles.

Add double support to the flex stage.

Put in some of the basic double supported needed in the front end.

Add generic support for version numbers in the preprocessor, and the core, compatibility, and es profiles.
