These classes don't show up well in generated headers (rdar://problem/20855568), can't actually be allocated from Objective-C (rdar://problem/17184317), and make the story of "what is exposed to Objective-C" more complicated. Better to just disallow them. All classes are still "id-compatible" in that they can be converted to AnyObject and passed to Objective-C, they secretly implement NSObjectProtocol (via our SwiftObject root class), and their members can still be individually exposed to Objective-C. The frontend flag -disable-objc-attr-requires-foundation-module will disable this requirement as well, which is still necessary for both the standard library and a variety of tests I didn't feel like transforming.
