Preparation of hooking up the new preprocessor.
- Added custom Diagnostics class. Routed all info-log messages via this new class.
- Added custom DirectiveHandler class. Moved directive-handling code to this class and routed the old path.
- Deleted lexer_glue because it is not needed anymore. The new preprocessor is almost ready!
- Killed a bunch of dead code related to PragmaTable.

Unroll for-loop if sampler array uses loop index as its index.
If inside a for-loop, sampler array index is the loop index, Mac cg compiler will crash. This CL unroll the loop in such situation. The behavior is:
1) If the for-loop index is a float, we reject the shader.
2) If it is an integer, we unroll the for-loop.
Things that should be done in the future are:
1) Add line number macros.
2) Add a limit to unroll iteration count.

Implemented validation for loop and indexing limitations specified by GLSL ES spec 1.0 Appendix A Section 4 and 5.
A couple of things to note:
- This CL only validates the "form" of loop and indexing. It does not detect number-of-iterations or out-of-bound access. This will require more involved analysis/heuristics.
- I haved combined SH_VALIDATE_CONTROL_FLOW and SH_VALIDATE_INDEXING into one flag - SH_VALIDATE_LOOP_INDEXING. Validating both together is much easier.
