06f8464fb5 Create linkage symbol nodes in the AST so a linker has access to all global objects that were declared, for error checking, etc. Use it now for all ins/outs/uniforms as well as gl_VertexID and gl_InstanceID. 
Also fixed a confusing name and added more 'const'.

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
