Unwind a hack whose stated purpose was to register a potential member edge from an extension to the extended type. In reality, this only registered a plain member dependency on 'deinit'. This edge is insufficient in isolation to cause a rebuild of a dependent file in the case where a type and its extension live in separate files. However, we appear to have been saved by the redundancy in edge registration because the lookup for the extended type will register a top-level or nominal dependency (for an unqualified or qualified reference respectively). The worry there is if a protocol conformance edge *should* flip a previously private nominal dependency edge to a cascading edge. In such a case, the old code would not have been able to make the cascading edge promotion, and we would have potentially miscompiled by not rescheduling dependent jobs.
