JIT: Always consider empty remainders to be dying in physical promotion (#88665)

Liveness takes a few shortcuts that means it doesn't always handle the
case where there is no remainder as the remainder dying, so add a
special case in StructDeaths::IsRemainderDying to take care of this
case.

Some minor improvements from more last-use copy omission are expected.
