Realized while working on another patch that this one is incomplete.

Problematic case: exit block is reachable from 2 or more exiting blocks with the values reaching along exit edges being different along each.  Need to determine correct exit value along the middle to unique exit block edge which is unhandled in this patch.  Value chosen here would likely be the value along the latch exit (ignoring early exit) if present and a crash if not.
