This test was pretty useless: it always enabled optimizations, so even if we did not emit nounwind for this function, LLVM would add it. That's why we agreed in #65020 that it could be removed.

In #65020 nobody knew why this branch should be needed. And all the tests behave as expected without it. So I think we should remove it.

nounwind tests and cleanup This is a follow-up to @pnkfelix' rust-lang#65020. In particular it adds some tests as @nagisa asked. It also does a cleanup that the original PR omitted to reduce backporting risks. I hope I finally managed to write an uncontroversial PR in this area. ;) This should not change any behavior, just test it better.
