Most of this is in updating the standard library, SDK overlays, and
piles of test cases to use the new names. No surprises here, although
this shows us some potential heuristic tweaks.
There is one substantive compiler change that needs to be factored out
involving synthesizing calls to copyWithZone()/copy(zone:). Aside from
that, there are four failing tests:
Swift :: ClangModules/objc_parse.swift
Swift :: Interpreter/SDK/Foundation_test.swift
Swift :: Interpreter/SDK/archiving_generic_swift_class.swift
Swift :: Interpreter/SDK/objc_currying.swift
due to two independent remaining compiler bugs:
* We're not getting partial ordering between NSCoder's
encode(AnyObject, forKey: String) and NSKeyedArchiver's version of
that method, and
* Dynamic lookup (into AnyObject) doesn't know how to find the new
names. We need the Swift name lookup tables enabled to address this.
In modern ObjC Protocol's object-ness is vestigial, and its class object isn't even visible from newer runtimes, so we can't use it as type metadata. Import it as a foreign class so that we make our own artificial metadata. Fixes <rdar://problem/17303759>.

<rdar://problem/17303759> -- we need to do something special for the Protocol type's metadata, because its ObjC class object is hidden.
