Thanks for reviewing, @gysit !

You are right about the LangRef description. However, I noticed that `llvm::MDBuilder::createAnonymousTBAARoot` creates a self-referencing distinct node, and the verifier seems to accept it.

My implementation matches that pattern to be consistent with how LLVM typically builds anonymous roots. That said, if you prefer to strictly follow the LangRef text (using `distinct !{}`), I am happy to switch to that.
