If there's some reason why this needs to be a tripple loop, I'm not
seeing it. As far as I can tell, all the inner-most loop does is look
for the next remaining block not already in cur_level->blocks. There's
no reason to re-walk the whole set every time just to do that.

Hash set ordering is non-deterministic so any time we make a decision
that may affect the final structure or order of instructions, we want to
use a sorted list of blocks.

I find the ternary a bit hard to read. The optimization is fairly
obvious but the way it's coded makes things more dense than they
probably need to be.

I'm trying to reduce exec_list usage in NIR. Also, util_list has some
better helpers for a bunch of the operations this pass needs.

It's really hard to track in this pass which sets are getting ralloc'd
off which other sets. To avoid leaks, just pass a mem_ctx around
everywhere and ralloc almost everything off the one context. We do keep
using recursion a few places where it's crystal clear what the parent
relationship is.
