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.
includes a number of QoI things to help people write the correct code. I will commit
the testcase for it as the next patch.
The bulk of this patch is moving the stdlib, testsuite and validation testsuite to
the new syntax. I moved a few uses of "as" patterns back to as? expressions in the
stdlib as well.

We have an SPI between the Swift compiler and Foundation based on the
SWIFT_SDK_OVERLAY_FOUNDATION_EPOCH preprocessor macro that allows us to
request the new API. rdar://20270080 tracks removing it.

Require 'as' when converting from Objective-C type to native type (but
continue to allow implicit conversion from native to Objective-C). This
conversion constraint is called ExplicitConversion; all implicit
conversions are covered by the existing Conversion constraint. Update
standard library and tests to match.

Diagnose cases where the use of @objc will produce Objective-C methods
that end up overriding an Objective-C method in a superclass, when
that override is not properly represented as an override in the Swift
type system. This can happen when the Objective-C methods are produced
by different kinds of entities. For example:
class Super {
@objc var property: Int
}
class Sub : Super {
@objc func setProperty(property: Int) { }
}
In Swift, Sub.setProperty and Super.property are completely
unrelated. However, both produce an Objective-C instance method with
the selector "setProperty:", so we end up with unexpected overriding
behavior. Diagnose this whenever it occurs, regardless of the kind of
@objc entity that produced the Objective-C methods: initializers,
deinitializers, methods, properties, or subscripts.
Implements the rest of the intended functionality of
rdar://problem/18391046, with the caveat that there are two remaining
classes of bugs:
1) Superclasses defined in a module (or imported from a Clang
module) aren't handled properly yet; we might not see those methods.
2) We won't properly detect all of these failures when the methods
are scattered across different source files in the same module.

Initializers for non-final classes will soon need to be 'required' to
conform to an initializer requirement in a protocol, so start
marking imported initializers from Objective-C protocols as
'required'. This is part of <rdar://problem/17408284> and
<rdar://problem/17415607>.
Swift SVN r20428
This fixes a case where the Swift-variadic and C-varargs versions of
various initializers were superseding each other
<rdar://problem/16801456>.
It also uncovered some more cases where we weren't getting quite the
right semantics for factory-methods-as-initializers, which are also
fixed here.

In the lit.site.cfg, if a MODULES_SDK is available, add a '%sdk' substitution and enable REQUIRES: sdk tests. Add some tests under test/Interpreter/SDK to test some basic ObjC interop features.
