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
