When setting the signature conformances in a NormalProtocolConformance, do so progressively rather than waiting until all of them are computed. This allows later requirements to refer to earlier conformances.
…ection. Introduce (recursive) constraints that make the *Collection constraint of SubSequence match that of its enclosing *Collection, e.g., MutableCollection.SubSequence conforms to MutableCollection. Fixes rdar://problem/20715031 and more of SR-3453.
