David Majnemer c0f2b8b528 IndVarSimplify: Don't let LFTR compare against a poison value ... LinearFunctionTestReplace tries to use the *next* indvar to compare against when possible. However, it may be the case that the calculation for the next indvar has NUW/NSW flags and that it may only be safely used inside the loop. Using it in a comparison to calculate the exit condition could result in observing poison. This fixes PR20680.
