Provide a JITMemoryManager derivative which puts all generated code into
one memory pool instead of creating a new one each time code is generated.
This saves significant memory per shader as the pool size is 512K and
a small shader occupies just several K.
This memory manager also defers freeing generated code until you tell
it to do so, making it possible to destroy the LLVM engine while keeping
the code, thus enabling future memory savings.

I saw that LLVM internally uses its global context for some things, even
when we use our own. Given ours is also global, might as well use
LLVM's.
However, sepearate contexts can still be enabled with a simple source
code modification, for when the need/benefit arises.

Many instructions implicitly update the accumulator on Gen < 6. The instruction
scheduling code just calls add_barrier_deps() for each accumulator access on
these platforms, but a large class of operations don't actually update the
accumulator -- mostly move and logical instructions. Teaching the scheduling
code about this would allow more flexibility to schedule instructions.

The M_PI*f macros used a preprocessor paste to append 'f'
to M_PI defines, which works if the values are only numbers
but breaks on OpenBSD where M_PI definitions have casts
and brackets to meet requirements of a future version of POSIX,

As far as I can tell, Mesa hasn't had a convenient way to dump ARB_vp/fp
source until now. Using MESA_GLSL=dump is convenient, since it means
you can use a single environment variable to dump a program's shaders,
no matter which language they're written in.

The point of copytexsubimage_using_blit_framebuffer is to use a hardware
accelerated BlitFramebuffer path. If that fails, we shouldn't do a
swrast blit---we should try our CTSI fallback code.
This is especially important for i965 and GLES, where we don't even
create a swrast context.

This is the only case where a fs_reg in brw_fs_visitor is used during
optimization/code generation, and it meant that optimizations had to be
careful to not move pixel_x/y's register number without updating it.
Additionally, it turns out we had a couple of other UW values that weren't
getting this treatment (like gl_SampleID), so this more general fix is
probably a good idea (though I wasn't able to replicate problems with
either pixel_[xy]'s values or gl_SampleID, even when telling the register
allocator to reuse registers immediately)
