David Majnemer 1ade0f0faa IndVarSimplify: Allow LFTR to fire more often ... I added a pessimization in r217102 to prevent miscompiles when the incremented induction variable was used in a comparison; it would be poison. Try to use the incremented induction variable more often when we can be sure that the increment won't end in poison.
