44e8cae80a Allow ES version 100 to redeclare built-in functions.

f2ee3dd46a Add full support for uniforms with initializers, including intra-stage link validation of aggregate constant initializers. 
This included 
 - encapsulating aggregate constants
 - removal of constant-aggregate comparison algorithms, instead using a flattened and direct std::vector comparison
 - adding structure type comparison for independently declared structures that still might match types

9839e2440e Unify the 8 grammar productions for declaring variables. This greatly simplifies making changes for this set of productions. 
This change also naturally picks up redeclarations of built-in arrays and the addition of the remaining linker objects of const, arrays, etc.

337dbc7d8c Add basic intra-stage linking validation for matching types and qualification of uniforms/ins/outs/globals, function body duplication, and mixing ES/non-ES shaders. 
Still need to handle arrays and built-in redeclarations, and many more rules, but this puts the basics in place.

f5ebfb5f27 Test for and prevent any dead-code elimination, as all code is needed in the AST for static-use analysis.

05a7063007 Add optional configuration file for specifying (existing) limits. Details explained by usage statement. More limits to be added in the future.

b84b700d90 Basic infrastructure for redeclaring built-in variables (like gl_FragCoord) so shaders can change their type/layout. 
A modifiable copy is made at the shader's global scope.

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

807b8e3b82 Remove TIntermediate's dependency on infoSink, simplify folding of constant aggregates, and infoSink use in constant folding. 
Added a few deep aggregate constant folding testing cases.

d46b31fdc5 Give new scopes to non-compound (simple) if-then-else substatements, correcting scoping for declarations they contain. 
Also, updated several tests and the Todo list.

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.
