llvmpipe: export the tgsi translation code to a common layer

the llvmpipe tgsi translation is a lot more complete than what was in
gallivm so replacing the latter with the former. this is needed since
the draw llvm paths will use the same code. effectively the proven
llvmpipe code becomes gallivm.

-/**
- * @file
- * Blend LLVM IR generation -- AoS layout.
- *
- * AoS blending is in general much slower than SoA, but there are some cases
- * where it might be faster. In particular, if a pixel is rendered only once
- * then the overhead of tiling and untiling will dominate over the speedup that
- * SoA gives. So we might want to detect such cases and fallback to AoS in the
- * future, but for now this function is here for historical/benchmarking
- * purposes.
- *
- * Run lp_blend_test after any change to this file.
