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.

I suspect there is a subtle reason why this is the wrong thing to do.

The issue I am trying to address is glBlitFramebufferANGLE generating an error when bliting from a GL_RGB8_OES renderbuffer to a GL_RGB texture bound to the read framebuffer and draw framebuffer respectively. It verifies that both surfaces have the same underlying D3DFMT but GL_RGB8_OES renderbuffers are backed by X8R8G8B8 and GL_RGB textures were previously backed by A8R8G8B8.

Since textures cannot as far as I know be created GL_RGB8_OES, it would be useful to have a way to blit from a GL_RGB8_OES renderbuffer to a GL_RGB texture.

Only initialize through a temporary variable if the same symbol name is used in the initialization expression.
TRAC #13627
The previous patch can generate a lot of unnecessary temporary variables. By first checking whether the same symbol name is reused the clutter is reduced to an absolute minimum (typical shaders won't rely on this odd GLSL semantic behavior so the workaround is hardly ever needed).

TRAC #13627
GLSL allows to write things like "float x = x;" where a new variable x is defined and the value of an existing variable x is assigned. HLSL uses C semantics (the new variable is created before the assignment is evaluated), so we need to convert this to "float t = x, x = t;".

- lexer and parser reentrant
- line number handling automatic

Caveats:
- The preprocessor is still not thread-safe and full of bugs. I have another not-yet-ready patch to replace the preprocessor.
- The grammar files use options that are not supported by the old versions of flex and bison checked into compiler/tools. So I need to check-in the generated lexer-parser along with a shell script to generate them.

Fixed infinite loops and buffer overflow in byte_scan when scanning for integers and floating-point numbers.
- The byte_scan and associated functions are not very well written. I tried to clean them as much as possible without re-writing the whole thing.
- Replaced lBuildFloatValue function with atof. lBuildFloatValue was returning incorrect value anyway. The only reason it was working so far because we never used that value.

I believe we don't support version 1 since we are missing things like the fixed function pipeline.

This is motivated by consistency with other EGL implementations, which return a v1 context if the EGL_CONTEXT_CLIENT_VERSION attribute is not specified.
