Sorry for messing you around here, but we've just noticed there are functions in MachineInstr that should be able to handle this for you. Specifically addRegisterKilled (make sure AddIfNotFound is false) and clearRegisterKills can replace the inner loop entirely (we think). They should also handle register aliases, which is probably a good thing.
