b603f918a4 Put all glslang internals (but not the external interface) into the glslang namespace.

c027579631 Put in infrastructure for tessellation, geometry, and compute stages, and partially flesh out with built-in functions. 
Added the built-in functions EmitVertex(), EndPrimitive(), barrier(), memoryBarrier(), memoryBarrierAtomicCounter(), memoryBarrierBuffer(), memoryBarrierImage(), memoryBarrierShared(), and groupMemoryBarrier().

Have not added any new built-in variables.

Also changed the linear performance relateToOperator() to a high-performance version.

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

fddf3ce3a1 Unify constant floats and constant doubles; they can all be constant doubles.

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.

ad3663be1f Add ES 300 built-ins trunc, round, roundEven, modf, isnan, isinf, floatBitsToInt, floatBitsToUint, intBitsToFloat, uintBitsToFloat, packSnorm2x16, unpackSnorm2x16, packUnorm2x16, unpackUnorm2x16, packHalf2x16, and unpackHalf2x16, and new form of min, max, clamp, and mix.

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.
