This reminds me, could you do something similar to clean up the
kill_emitted flag in brw_fs_visitor? It's kind of a hack, and I seem to
recall that we wanted to do the kind of front-end plumbing you're
already doing here.
Not to mention there already seems to be a UsesKill flag...
I thought there were two problems with that. First, we try to optimize
away the kill instructions, and it's hard to unset a flag. Second,
there are other things that cause kill_emitted to get set (alpha test?).
