It already doesn't do that at -O0.
This part of the thread was about not skipping prologues at all; we
can't do that even with GCC, because the debug info says arguments
live in their stack slots. But they're in different incoming
locations until the end of the prologue (registers or other stack
slots). I think we'd want debug info which only specified the
incoming locations and the local stack slots, not every load into a
register - which is probably what GCC tries to produce.
