Throw a dead flag in there as well since these are just clobbers.

    Change MachineInstrBuilder::addReg() to take a flag instead of a list of
    booleans. This gives a better indication of what the "addReg()" is
    doing. Remembering what all of those booleans mean isn't easy, especially if you
    aren't spending all of your time in that code.
