Fix a subtle bug in DeadMachineInstructionElim's liveness
computation. A def of a register doesn't necessarily kill
live super-registers.

isReg, etc., from isRegister, etc.

Refactor the logic for testing if an instruction is dead into a
separate method.

dead loads.

Now that DeadMachineInstructionElim is basically working
correctly, it's not necessary to explicitly remove registers
from their use-def lists.

Track local physical register liveness. This is not the most
efficient implementation possible, but it's pretty simple and
good enough for the time being.

Don't consider instructions with implicit physical register
defs to be necessarily live.

Add a new MachineInstr-level DCE pass. It is very simple, and is intended to
be used with fast-isel.
