[PATCH] D106784: [ADT] function_ref captures function pointers by value

[Chandler Carruth via Phabricator via llvm-commits]

chandlerc added a comment.

An alternative would be to delete this overload and insist callers pass a lambda that itself calls the desired function. This makes the user of `function_ref` more verbose, but it avoids having two dynamic dispatches (I think).
