Store type, protocol, and conforming decl in ProtocolConformances.

Browse Source 
This makes ProtocolConformances fully self-identifying so that a ProtocolConformance* pointer alone is enough to identify a conformance as a link entity.

We currently lose the conforming decl during deserialization because trying to deserialize a reference to an ExtensionDecl asserts out. I'll bug Jordan about that.
