Fixed dangling pointers in Surface.

When the surface is reset, either because of device lost or a window
resize, and any of these fail:

CreateDepthStencilSurface
CreateTexture

Some subsset of mSwapChain and/or mDepthStencil would be left
uninitialized. This seemed to happen frequently on WIndows XP boxes.

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.

For textures that are not already render targets, use the CPU to filter them and mark them as dirty.

I tested it by modifying the "mip_map_2d" demo to call glGenerateMipmap instead of generating the mipmaps itself. I also used the debugger to force it to take the render target path and verified that it still worked.

We've been having problems with the display being reset when video memory pressure is heavy with one of our demos. This patch made a noticable improvement on Vista but I don't think it will necessarily help on XP.

Moved the global-pool-allocator to TCompiler so that all memory allocated by the compiler can be de-allocated. Earlier the global-pool-allocator kept accumulating memory from all compilers (symbol-table in particular). The memory was only de-allocated when gpu-process exited or ShFinalize() was called. This was a problem for Chromium which keeps the GPU process around for the browser session. Now the memory is de-allocated as soon as the compiler is deleted, which happens when a tab is closed.

Removed actions for generating parser-lexer now that they have been checked in. Also removed hooks to pull cygwin - it was only required for flex and bison that are not required anymore. If a developer needs to modify grammar files, he is expected to install cygwin.
