Refactored the way symbol tables are initialized and stored. This was done in response to the addition of EShSpec.
Symbol table entries depend on three things - language, spec (not now but may eventually), and built-in resources.
We used to build two global symbol-tables - one for each language. During each compile, one of the symbol table was
copied and resource-specific stuff was added. I have moved the symbol table to TCompiler that gets initilized when
compiler is created and reused for each compile. This makes it much cleaner and extensible in case a spec requires
special entries to be added to the symbol table.

PS: Sorry for the long CL, but all of it needed to be done in one CL. I have verified that everything still compiles
and passes all conformance tests.

I found that when I switch desktops, GetRenderTargetData will return D3DERR_DEVICELOST. It is unclear to me whether ReadPixels should report a GL error in this case and if so, which one. I went with GL_OUT_OF_MEMORY. Let me know if that's wrong.

This change is not sufficient to make eglGetError report EGL_CONTEXT_LOST. For a program doing exclusively offscreen rendering, ReadPixels might be the only place where D3DERR_DEVICELOST can be detected. The GLES code can't call egl::setCurrentError though. I'm not sure how to fix that.

TRAC #12641
The precision of compiler temporaries doesn't require checking,
and would be hard to determine at parse time. We only require
correct precisions for declarations, which is checked separately.
So we can safely remove the check for binary operations.

This was caused by the change from printf to iostream printing.
Sets the float formatting to "default" which is neither fixed or scientific and request 8 digits of precision.
This appears to be mostly equivalent to the previous "%.8g".
If the non-fractional case, we set it to fixed and use 1 unit of precision after the decimal.

Removed the dependency of compiler on common. This is done to make compiler self-sufficient so that it is easier to consume by external developers. I tried to replace all instances of assert by simply redefining assert(x) to ASSERT(x), but was getting a lot of compile errors. I still need to investigate that.

ShInitialize/ShFinalize is designed to be called once per process, or it would crash at random locations. I changed ShFinalize() to properly cleanup and reset global variables so that they can be called multiple times. I think that the compiler setup is much more complicated than it needs to be. It unnecessarily uses global variables. A custom pool allocator is overkill too.
