lima/ppir: remove use of live_out
The live_out set was serving mostly as a temporary storage of data
propagated from the next instructions.
If we do an early copy to preserve the instruction live_in set and
propagate the liveness information directly to the live_in set, we can
skip having a live_out set entirely.
