aa215e7e54 made sure we didn't try to construct Sets and Dictionaries with a non-Hashable key. However, that commit was a little too restrictive: there was no handling for imported generic parameters that were constrained to inherit from NSObject. Fortunately, recovering that information is fairly straightforward. rdar://problem/33222646
