Hmm, at second tought I guess statement gets improperly updated for lack of
side effect in fixup_cfg. Will look into it.
Even that is however not enough for function to be optimized away since we
don't re-do IPA after local optimization. This would require even more
complicating the optimization queue. So it is hard to solve fully.
