Resilient conformances now put all witnesses into the resilient witness table, so optimize away the witness table pattern for such cases. Teach the runtime to fill in the protocol conformance descriptor, because that’s the only bit of real information that would be in the pattern. This is a minor optimization enabled by rdar://problem/46282080.
