Add warning-suppression flag.  Combined with relaxed errors, so an enum can be used instead of many bools.

Add compilation mode flags for forward-compatible contexts and relaxed error checking.  These initiate as arguments to ShCompile() and both default to being off.

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.

Add ES 300 matrix operations: outerProduct, determinant, inverse, and transpose, and missing ES 300 limit gl_MaxFragmentInputVectors.

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

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

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.

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

Used this for precision keywords and double matrix keywords.

Also added a few missing reserved words.

Also removed redundant "syntax error" when there is a parse error.

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.
