Jordan Rose f5a6ac96cb [test] Add a test for the tricky circularity in SR-5191. (#11685)
This was fixed by 897effe, which I had originally thought would be a
no-functionality-change commit because it just made things lazier.
Turns out requirement signature deserialization can result in
circularity with sufficiently cross-referential conformances.

This isn't exactly a reduced test case because it still depends on
subclassing NSObject, which probably means there are hidden
dependencies on conforming to standard library protocols. But it's
better than nothing.
