Timur Kristóf f6b2db298f ac/nir: Refactor and optimize the repacking sequence.
According to feedback, the terminology with "exclusive scan"
and "reduction" is difficult. Change it to use "repack" instead,
which better fits what this sequence is actually used for.

The new sequence stores only 1 byte / wave to LDS, and uses packed
instructions to produce the results. This has lower latency and
fewer instructions than what we previously had.
