I ended up reverting this patch in https://github.com/llvm/llvm-project/commit/a4772cbaf0dc717ab6b4639272ca2910897613f0, because I reduced another infinite loop (https://github.com/llvm/llvm-project/issues/56203) to it as well, which makes it the third one. It's probably not possible to reliably prevent infinite combine loops in this area with a dominator tree.
