LGTM.

That said the medium to short term plan is to get rid of kill flags, which means RegisterScavenger::forward() and RegisterScavenger::unprocess() will not any more (or at least give you very conservative results which are probably not too useful). I'd recommend to switch your code to LiveRegUnits/LivePhysRegs (in case you don't need emergency spilling) or RegisterScavenger::backward() instead!
