- Add LiveVariables::replaceKillInstruction. This does a subset of instructionChanged. That is, it only update the VarInfo.kills if the new instruction is known to have the correct dead and kill markers.

- CommuteInstruction copies kill / dead markers over to new instruction. So use replaceKillInstruction instead.

Also, if LV isn't around, then TwoAddr doesn't need to be updating flags, since they won't have been set in the first place.

SelectionDAG::SelectNodeTo in the instruction selector. This
updates existing nodes in place instead of creating new ones.
Go back to selecting ISD::DBG_LABEL nodes into
TargetInstrInfo::DBG_LABEL nodes instead of leaving them
unselected, now that SelectNodeTo allows us to update them
in place.
