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.

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.

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

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

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.

 - 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

Ensure the shared symbol table levels are read-only to make multi-threading safe.  Also removed inadvertent extra copies of the symbol table shared across all stages.

Add link validation infrastructure for multiple compilation units per stage.  Includes a new, straightforward, C++ interface to the front end.

Some rationalization of TIntermediate (to own it's own tree root) and TParseHelper for better encapsulation.  Needed by some upcoming intra-stage link validation.

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.

Restore TDebugOptions, as code consuming this interface is still using it, even though the front-end proper no longer uses it.

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.

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.

Allow unsigned int in the "location = " grammar, and generally improve recognition of numeric literals to be up to spec.
