freedreno/ir3: lower phi webs to regs
nir's from_ssa pass is much better at avoiding inserting extra moves
than our logic is. And lowering phi webs to regs just treats anything
involved in a phi web as an array of length=1. Which with previous
array related fixes in RA/etc ends up working out quite well. This cuts
down on extra instructions and also helps with register pressure.
