> I missed the clang patches, but it looks as if they didn't update clang's `LanguageExtensions.html` to document the new builtins - please can you add them?

Looks `__atomic_fetch_nand` is a GNU compatible builtin and we have mentioned it roughly since https://reviews.llvm.org/D10847. Do we have to document these GNU compatible `__atomic_*` builtins in another section?
