Evan Cheng 4ff3f1cc57 - Fix a subtle bug in RemoveCopyByCommutingDef. ALR is the live range where the source is defined; BLR is the live range which is defined by the copy.

If ALR and BLR overlaps and end of BLR extends beyond end of ALR, e.g.

then do not add kills of A to the newly created B interval.
- Also fix some kill info update bug.
