We no longer require mangling suffixes for intrinsic calls since https://github.com/llvm/llvm-project/pull/89172.

I don't think we should omit the mangling suffix when writing IR though, since that will obscure what actually happens without clear benefit. (For example, it would become very hard to actually figure out whether the correct mangling suffix was chosen or not.)

Can you please explain what the actual *problem* you are trying to solve is?
