…nature. When a requirement source involving a ProtocolRequirement element is built prior to the requirement signature of the protocol it references, we can end up with a requirement source whose steps don't reflect was is actually available via the requirement signatures. When building a conformance access path from such requirement sources, canonicalize on-the-fly using the requirement signatures (which have been/can be computed by this point) to produce a correct access path.
