The GenericSignatureBuilder is allowing unresolved dependent member types to creep into generic signatures, which eventually blows up in name mangling. Prefer to pick dependent member types that are fully-resolved when choosing anchors. This is a spot fix; a better approach would eliminate the notion of unresolved dependent member types entirely from PotentialArchetype. That's tracked by rdar://problem/35839277. Fixes rdar://problem/36549499.
