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.
Otherwise, people subclassing NSView will accidentally call NSView.print
when they're trying to call Swift.print.

If there is a method -foo: that's unavailable (for whatever reason), and we now
have a method -foo:error: that we'd like to import, it's okay to drop the error
parameter there. Overload resolution can handle filtering out the unavailable
method.

If 'x.init' appears as a member reference other than 'self.init' or 'super.init' within an initializer, treat it as a regular static member lookup for 'init' members. This allows a more explicit syntax for dynamic initializations; 'self.someMetatype()' looks too much like it's invoking a method. It also allows for partial applications of initializers using 'someMetatype.init' (though this needs some SILGen fixes, coming up next). While we're in the neighborhood, do some other correctness and QoI fixes:
- Only lookup initializers as members of metatypes, not instances, and add a fixit (instead of crashing) to insert '.dynamicType' if the initializer is found on an instance.
- Make it so that constructing a class-constrained archetype type correctly requires a 'required' or protocol initializer.
- Warn on unused initializer results. This seems to me like just the right thing to do, but is also a small guard against the fact that 'self.init' is now valid in a static method, but produces a newly-constructed value instead of delegating initialization (and evaluating to void).

...so that their modern NSError-based variants won't be imported using an
extra "error: ()" parameter. Apart from looking prettier, this avoids a
crash when overriding the "error: ()" versions, rdar://problem/21144509.
Once NS_REFINED_IN_SWIFT has been implemented we can probably use that instead.
Filed rdar://problem/21192039 to remove the hack at that point.
