Context for reviewers: after https://github.com/llvm/llvm-project/pull/204417 an internal test started failing. Upon further investigation it was determined that the fix in https://github.com/llvm/llvm-project/pull/204417 was a bit too broad and started forbidding allowed cases. I also took this opportunity to add many more corner cases for statement functions.

Note: with this change the original issue https://github.com/llvm/llvm-project/issues/203820 stays fixed.
