[RegisterCoalscer] Manually remove leftover segments when commuting def
In removeCopyByCommutingDef, segments from the source live range are
copied into (and merged with) the segments of the target live range.
This is performed for all subranges of the source interval. It can
happen that there will be subranges of the target interval that had
no corresponding subranges in the source interval, and in such cases
these subrages will not be updated. Since the copy being coalesced
is about to be removed, these ranges need to be updated by removing
the segments that are started by the copy.
