[PR103302] skip multi-word pre-move clobber during lra
If we emit clobbers before multi-word moves during lra, we get
confused if a copy ends up with input or output replaced with each
other: the clobber then kills the previous set, and it gets deleted.
This patch avoids emitting such clobbers when lra_in_progress.
