we can generate 32-bit scalar inverse_ballots from the boolean reduce lowering
which will blow up when trying to lower the resulting inverse_ballot with the
common lowering. but the assert can be quieted just fine.

this is the lowering from NAK, fixed up for common code. the existing code is
used for boolean scan/reduce. I make no guarantee that this works for subgroup
sizes other than 32.

this will be useful for AGX, which has many reductions (but not all) in
hardware with the logic too backend-specific to encode with bitflags.

Also, re-organize a bit to match the spec better. There are now
capabilities which need to be set to constant true which we didn't have
to se in the old caps struct and this makes it all more obvious.

I noticed some unnecessary 64-bit ints in shaders that were using doubles.
Perhaps there's a different missing optimization that should run on the
actual pack/unpack instructions before they're lowered, or maybe I'm just
lowering them too early, but these seem simple enough that we might want
them even for hand-rolled pack/unpack pairs.

The constant-folding definition and comments say that it takes the high
16 bits of the first source and low 16 bits of the second source, but
actually it's the opposite. The algebraic optimization, which actually
happens and needs to be correct, was correct but the comment above it
was wrong.
Note that in the way we use it when lowering multiplications, the
ordering doesn't matter.
