Slava Pestov 8b59660143 GSB: Don't infer requirements from type constructors in a protocol inheritance clause ...

This enabled a gross idiom that should not have been allowed in the first place:

    typealias G<T> = Any where T : P

    protocol P {}
    protocol Q : G<Self> {} // Q inherits from P now!

I'd like to ban this, assuming nothing is actually relying on this behavior.
