Jun Bum Lim 36c53fe147 [MachineCopyPropagation] Expose more dead copies across instructions with regmasks ...

When encountering instructions with regmasks, instead of cleaning up all the
elements in MaybeDeadCopies map, remove only the instructions erased. By keeping
more instruction in MaybeDeadCopies, this change will expose more dead copies
across instructions with regmasks.
