Personally, I find the expression "over-optimization" misleading: either we
have a compiler *bug*, which therefore is performing an incorrect
transformation, or we don't, thus the code is triggering undefined behavior
(which happens to show up at high optimization level). In either case, I don't
see "over-optimization".
