llvmpipe: Proper control flow builders.

New control flow helper functions which keep track of all variables
and generate the correct Phi functions.

This re-enables skipping the fs execution of quads masked out by
the rasterizer, early z testing, and kill opcode.

This yields a performance improvement of around 20%.
