Issue Description:
https://github.com/apple/swift/pull/9379 removed tests confirming collection's associated types conformed to appropriate protocols e.g. MutableCollection.SubSequence: MutableCollection. Now the compiler is enforcing these, so they were just generating warnings.
They should be replaced by tests checking the compiler is enforcing these rules (by trying to create invalid collections and checking the error messages).
