Jonas Paulsson 64599ac97e [MachineSink] Don't reject sinking because of dead def in isProfitableToSinkTo(). ...

An instruction should be sunk (if otherwise legal and profitable) regardless
of if it has a dead def of a physreg or not. Physreg defs are checked in other
places and sinking is only done with dead defs of regs that are not live into
the target MBB.
