e54c111c45 aco: always use p_parallelcopy for pre-RA copies
Most fossil-db changes are because literals are applied earlier
(in label_instruction), so use counts are more accurate and more literals
are applied.

0f31fa1b64 aco: skip value numbering of copies
Instead, copy-propagate through and remove them.

This improves value numbering in this situation:
a = ...
b = copy a
c = copy a
use(b)
use(c)
