Add and partially implement an interface for doing uniform reflection. It includes an AST traversal to identify live accesses.

It does not yet correctly compute block offsets, give correct GL-API-style type values, or handle arrays.

This is tied to the new -q flag.

+ Add new minimum maximums for gl_MaxVertexOutputComponents, gl_MaxGeometryInputComponents, gl_MaxGeometryOutputComponents, and gl_MaxFragmentInputComponents,
rather than relying on gl_MaxVaryingComponents. Also, corrected gl_MaxVaryingComponents to be 60 instead of 64.
+ Added gl_PrimitiveID as an input to fragment shaders.
- Added gl_FragCoord qualifiers origin_upper_left, and pixel_center_integer to modify the values returned by gl_FragCoord (and have no affect on any other aspect of the pipeline or language).
- including redeclaration of gl_FragCoord that adds nothing

- Added support for multi-sample textures through sampler2DMS and sampler2DMSArray support in texelFetch() and textureSize().
+ Broadened interface blocks from just uniforms to in and out interfaces as well.
+ Broaden array usage to include vertex shader inputs (vertex in).
