This is a loop optimization issue, not a jump threading bug. To really
optimize this loop well we will likely need the kinds of analysis found
in "Beyond Induction Variables", the classic paper describing loop flip-flops
and other interesting loop variables that are not simple induction variables.
Anyway, I'm removing this from the set of bugs related to jump threading.
