99296369d3 Add GL_EXT_frag_depth. 
git-svn-id: https://cvs.khronos.org/svn/repos/ogl/trunk/ecosystem/public/sdk/tools/glslang@24003 e7fa87d3-cd2b-0410-9028-fcbf551c1848

06a37c3964 Add GL_OES_standard_derivatives. Also added extension infrastructure that allows built-in symbols to be tagged with extensions and automatically error checked against them.

77d908af8a Added constant folding for relational (e.g. lessThan) built-ins, relational built-ins for uints, and bitwise ops for mixed scalars and vectors. 
Also, allow comments to precede "#version 100".

ab41fe5df6 Add redeclarations of built-in blocks. 
Note: lots of test results changed due to listing the members of a block when printing types.

e7c59c187c Add all built-in variables for all versions/profiles/stages of GLSL. Also, made more readable; declarations are cut and paste from the specs, with quotes around them. This does not include built-in constants yet (other than MaxClipDistances), just the non-constants.

e50441ad94 Make some portability improvements identified by Christophe: A few size_t, a couple "../Include", and a whole bunch of parenthesizing "(A && B) || (C && D)", because some compilers don't believe humans know && is higher precedence than ||.

5f753e0222 Full thread safety working: 
- don't use [] for map lookups, it can modify the map
 - copy up built-in symbols out of shared symbol table levels before modifying them
 - enforce shallow vs. deep TType copies
 - combine maxArraySize with the array dimensions vector, encapsulate
 - remove chaining of array types

c027579631 Put in infrastructure for tessellation, geometry, and compute stages, and partially flesh out with built-in functions. 
Added the built-in functions EmitVertex(), EndPrimitive(), barrier(), memoryBarrier(), memoryBarrierAtomicCounter(), memoryBarrierBuffer(), memoryBarrierImage(), memoryBarrierShared(), and groupMemoryBarrier().

Have not added any new built-in variables.

Also changed the linear performance relateToOperator() to a high-performance version.

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

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.
