f54b1f1e77 meson: Set build.rust_std 
This is needed because meson currently makes rust_std part of the build
environment and therefore per-arch.  This is a bit nonsense but it's not
too hard to work around.

edf015eb7f nak: Fix the encoding of OpShfl 
We weren't handling Zero.  Also, we need to mask immediates or else the
encoder blows up.  The hardware automatically masks them when they come
in as sources but when we get immediates, they're not guaranteed to fit
in the bitfield.

ed187b6e51 nak: Fix parallel copy handling in spilling 
Only consider copies with the right file.  Otherwise, the spill chooser
will blow up looking for the next use.  Also, we were marking
destinations as spilled when I ment to mark them as being in W.  This
was a right mess.  God thing to_cssa() was also broken so it wasn't
inserting nearly as many parallel copies as it was supposed to. 🙃

5b355ff25a nak: Fix opt_out 
It was converting instructions to/from Op which throws away predicates.
This meant that any instruction immediately after an OUT.EMIT would
loose its predicate (if any).  If an OUT.EMIT comes right before a BRA,
this results in the branch always getting taken.

While reworking things, I also totally reformatted the pass to make it
more readable IMO.
