Summary: While setting kill flags on instructions inside a BUNDLE, we bail out as soon as we set kill flag on a register. But we are missing a check when all the registers already have the correct kill flag set. We need to bail out in that case as well. This patch refactors the old code and simply makes use of the addRegisterKilled function in MachineInstr.cpp in order to determine whether to set/remove kill on an instruction.
