pan/bi: Pack csel4 opcodes
These are pretty straightforward but there's a lot of details to keep
straight. In the IR, we keep a general logical comparator and types
separately; in the hardware, the type gets fused with a (much more)
limited number of comparators. So there's a fair bit of code here to
account for these differences, fusing in the type information, and
changing up argument order as necessary to make it actually correct.
Anything to save a bit!

pan/bi: Implement csel fusing
When generating csel instructions, we can peak to see what condition is
being used. If we're using a "nice" condition, we can fuse it in with
the csel itself, ideally letting the condition itself be DCE'd away.

We rewrite BIR_INDEX_CONSTANT (and _ZERO) to preassigned constant ports

raised here, unfortunately, and the implementation here is woefully
incomplete with a nasty hack for loads... nevertheless, it's somewhere
to start.

We're not totally sure what's up with this but Connor says if you

pan/bi: Implement FMA/MOV without modifiers
We split off MOV from FMOV since the canonical move on Bifrost doesn't
accept modifiers. (We can still do fmov, but with something like add-0.)
This will also make copyprop a little nicer, I think. Anyway, the
non-modifier version we can implement as-is for FMA.
