This branch defines a gallivm_state structure which contains the
LLVMBuilderRef, LLVMContextRef, etc. All data structures built with
this object can be periodically freed during a "garbage collection"
operation.
The gallivm_state object has to be passed to most of the builder
functions where LLVMBuilderRef used to be used.

With this commit all explicit Phi emission is now gone.

No need for for a flow stack anymore.

Simply rely on mem2reg pass. It's easier and more reliable.

Don't branch more than once in quick succession. Don't branch at the
end of the shader.

|
Refactor the code to make this easier.

the loop was doing a NE comparison which we could have skipped if the prim
was triangles (3 verts) and our step was 4 verts. also fix offsets in conversion
to aos.

The llvm wrapper wasn't really an OS thing.
Use lp_bld.h for now but we eventually should rename/re-prefix all the
files/functions in the gallivm/ directory.

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.
