Christopher Rogers' (good) work in 49fd5acbb2 caught places where
the Swift compiler was allowing a @class to resolve to a Swift class
even if that class had a conflicting Objective-C name, or wasn't
intended to be exposed to Objective-C at all. Unfortunately, this
broke source compatibility in projects where people were relying on
this. Restore that functionality, but only as a fallback; matching the
Objective-C name is better than matching the Swift name.
