Don't add <imp-def> operands during register rewriting.
LiveIntervals already adds <imp-def> operands for super-registers when a subreg
def defines the whole register. Thus, it is not necessary to do it again when
rewriting.
In fact, the super-register imp-defs caused miscompilations because the late
scheduler couldn't see that the super-register was read.
We still add super-reg <imp-use,kill> operands when rewriting virtuals to
physicals.
