[llvm] [ValueTracking] Handle range attributes in isGuaranteedNotToBeUndefOrPoison (PR #88199)

This change doesn't make sense. If the argument is `noundef range` then the argument indeed cannot be poison, as a poison value (including one produced by the range annotation) would result in immediate UB.
