b00bc829 - [ClangImporter] Fall back to Swift class names when resolving @class (#27921)

[ClangImporter] Fall back to Swift class names when resolving @class (#27921) Christopher Rogers' (good) work in 49fd5acbb2bf 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. rdar://problem/56681046
