08e0c086c8 HLSL: fix GS implementation for EP wrapping 
The prior implementation of GS did not work with the new EP wrapping architecture.
This fixes it: the Append() method now looks up the actual output rather
than the internal sanitized temporary type, and writes to that.

75694fdacd Implement implicit conversions of function-call arguments (both in and out) as explicit conversions in the AST, through handleArgumentConversions(). 
Also
 - uniformly handle EvqConstReadOnly as an input argument in a function, with 
   isParamInput() and isParamOutput() queries in TQualifier.
 - provide a makeTemporary() in TQualifier, for erasing original qualification when making a temp
 - provide a makeInternalVariable() call to make a shader variable not seen in the shader source

457145ded5 Have block members use EvqVaryingIn rather than EvqIn, etc., confining the EvqIn-class of qualifier just to parameters and parse time (before it's known if something is a parameter). Also, have member error messages report their actual line, rather than the block's line.

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

5d3e2e35b6 Support suffixes for floats and doubles (none were supported in 110). 
Add preprocessor support for parsing doubles.

Add double support to the flex stage.

Put in some of the basic double supported needed in the front end.

Add generic support for version numbers in the preprocessor, and the core, compatibility, and es profiles.

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.
