@objc inference was looking at unavailable requirements---for which we don't ever record witnesses---at a point when it is no longer possible to record such a witness. This is a targeted fix; we need to tackle the issue of unavailable and optional requirements more thoroughly. Fixes SR-3917 / rdar://problem/30474860.
