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

fb5f7eadfa Improve robustness for symbol downcasts by moving to a "getAs" infrastructure and doing more error checking.

46eaf4939e Support multiple default versions, to enable ES vs. desktop contexts, for shaders missing a #version statement. 
This also moved some parseContext code from the flex file to the proper C++ file.

f0fdc53e2a Implement non-square matrices, and make a few type improvements. Cleaned up a few old issues. Added two tests. 
Details
 - added all the new non-square types
 - separated concepts of matrix size and vector size
 - removed VS 6.0 comments/workarounds
 - removed obsolete concept of matrix fields

59ddbafb62 Have non-ES profiles always use EpqNone (no precision qualifier) rather than using highp. This keeps precision qualifiers out of error messages, IL dumps, etc., and avoids the precision propagation algorithm.

9fd55bd338 Add a new shader-versioning infrastructure capable of handling multiple profiles, desktop/ES, many versions, features coming and going in different versions across different profiles, and extensions. 
NB: *Use* of this infrastructure is so far only skeletal.

Fixed a few typos and minor issues along the way.

e95ecc54fa 1) Improve error recovery from arrays sized with a non constant. 2) Add double vectors to the lexer. 3) Default to vertex shaders for unrecognized file name suffixes. 
Also fix issue where the keyword "shared" conflicts with the layout qualifier identifier "shared" by allowing the keyword in the layout qualifier identifier list.

fabf3e4058 Add arrays of arrays grammar, and adapt existing 1D array semantics to keep working as before. 
Also add buffer and shared keywords and grammar, which brings the grammar up to 4.3.

N.B. There is a problem for "shared": it is both a keyword (as a storage qualifier) and an identifier (for layouts).

e320a1854b Remove the pack/unpack languages and bring grammar up from 1.1 to 4.2 and fix the affected 1.1 productions and semantics to still work correctly for 1.1 shaders. 
For 4.2, largely, it is only the grammar that is working.  Productions and semantics are mostly missing.  Lexical analysis is mostly done, but not in the preprocessor, which still can't handle uint and double literals.

The grammar and token names are reorganized to match the specification, to allow easier comparison between the specification and the working grammar.
