Parallel copy code is from ir3_lower_parallel_copy.c. This was attributed in the
commit message but lost in the copyright header due to a copypaste mistake.
Rectify this.

Lifted from ir3. Algorithm is the same; the data structures and interface are
lightly modified to decouple from ir3's IR.
Sequentializing parallel copies after RA is tricky. ir3's implementation works
well enough, so I use that one.
Original implementation by Connor Abbott.
