Callsites could be marked as `builtin` while calling `nobuiltin` functions. This can lead to problems, if local optimizations apply transformations based on the semantics of the builtin, but then IPO treats the function as `nobuiltin` and applies a transform that breaks builtin semantics (assumed earlier). To avoid this, mark such functions as maybey-derefined, to avoid IPO transforms on them that may break assumptions of earlier calls.
