It can be used as a last resort. It depends on whether various rtl
passes take care of hard registers or not.
I'd like to wait your pre-allocating pass. It's surely cleaner than
that a bit unreliable artifact in prepare_move_operands. Perhaps
both can be almost equaly invasive to the release branch. If the pass
is enough simple and can give good results, it may be a safer bet,
especially when we are in transition to LRA.
