Jakob Stoklund Olesen 8137fd6975 Update SplitEditor API to reflect the fact that the original live interval is

Keeping the original interval made sense when the split region doesn't modify
the register, and the original is spilled. We can get the same effect by
detecting reloaded values when spilling around copies.
