Clean the implementation of GL_EXT_texture_shadow_lod. 
Move the parameter verifictation to a centralized place where all the builtins
are verified for correctness.

Add verification for the new builtins with version and extension check
These builtins are supported on GLSL since version 130 and GLES since
version 300.

0bbe74c709 Use temporary parser for mangled names 
Use a temporary parser to retrieve the mangled names of specific
function overloads. This is necessary for GL_EXT_texture_shadow_lod.

adfcaba7ae Fix ODR violations 
On a shared build, these symbols exist in both libglslang.so and
libSPIRV.so, leading to an ODR violation at runtime.

e66dace97e Web: First pass of tabling the built-in function declarations. 
Doing this much saved about 11.5K, including adding all the infrastructure.

0ae28ea647 Add base class TParseables for intrinsic / builtin generation. 
Add stubbed HLSL derivation.  GLSL derivation is still called TBuiltIns,
for historical compatibility.

e50441ad94 Make some portability improvements identified by Christophe: A few size_t, a couple "../Include", and a whole bunch of parenthesizing "(A && B) || (C && D)", because some compilers don't believe humans know && is higher precedence than ||.

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

db6b9117a6 Implement modern (130 and above) texturing. About 250 functions for 3.0, over 500 for 4.3, created programmatically. Handles all 3.0 functions, almost all 4.3 functions.

bd0747d6f0 Built-in symbol tables now lazily evaluated, and driven by per version, per profile input. Got all ES 100 and ES 300 built-in symbols correct. 
This includes
 - doing prescan of shader to know version/profile before parsing it
 - putting precision qualifiers on built-in ES symbols
 - getting most built-in state correct for core/compatibility/missing profile
 - adding gl_VertexID and gl_InstanceID, among other ES 300 built-in symbols
 - adding the ES 300 gl_Max/Min constants
 - accepting shaders that contain nothing but whitespace without generating an error
