Matthias Braun c41acffe22 RegisterCoalescer: Fix removeCopyByCommutingDef with subreg liveness ...

The code that eliminated additional coalescable copies in
removeCopyByCommutingDef() used MergeValueNumberInto() which internally
may merge A into B or B into A. In this case A and B had different Def
points, so we have to reset ValNo.Def to the intended one after merging.
