[Change-Id: Ic349022bb99ef91f5396e462ade0366bc772ae02](#123531) moved isDead() from DeadMachineInstrElim to MachineInstr . In the process of moving, I reordered the checks to improve chances of early exit, but this has caused a slight increase in compile time.

This PR reverts back to the original order of checks.
