Add an assertion to make PR7542 fail consistently.
...
LiveInterval::overlapsFrom dereferences end() if it is called on an empty
interval.
It would be reasonable to just return false - an empty interval doesn't overlap
anything, but I want to know who is doing it first.

another return instruction returns a different constant. This is a
