[PATCH] D130224: [Clang][Attribute] Introduce maybe_undef attribute for function arguments which accepts undef values

[Nuno Lopes via Phabricator via cfe-commits]

nlopes added a comment.

Would it be possible to implement this by dropping the `noundef` attribute rather than emitting a freeze? Seems like a much better option to me.
