This introduces _dictionaryUpCast and _dictionaryBridgeToObjectiveC,
which will be used for upcasting for non-bridged and bridged key/value
types, respectively. _dictionaryUpCast is a horrible copying O(n)
implementation where we should be able to provide an O(1)
implementation, and _dictionaryBridgeToObjectiveC is similarly
awful. Hence, this is not for <rdar://problem/16852016>, but is merely
a stub to let us make progress on upcasting in the frontend
(<rdar://problem/17289296>).

instead of importing them as _Nil (which will be going away when nil becomes an expr).
You now get an error saying:
error: 'NULL' is unavailable: use 'nil' instead of this imported macro
This is pretty cool all around, except for the GCD macros that need to be fixed, I'll
handle that as a follow-up.

Narrowly address the problem of downcasting an array to an array of
Objective-C existentials by checking conformance for Objective-C
protocols. Addresses <rdar://problem/17165071>, but this area still
needs a lot of work.

rangeOfCharacterFromSet(_:options:range:)
The underlying Objective-C API could return an NSRange of NSNotFound. Swift's
String.Index can not represent that, so change the API to return an optional
Swift Range<Index> instead.

stringWithBytes(_:length:encoding:) was passing an array to Objective-C
incorrectly, and a garbage NSString was being constructed as a result.
Unhide the initializer was accidentally hidden.

Two of the String conversion tests want to check the case where none of CF's
fast-access functions succeed. In one of these tests CF's fast-access functions
will always succeed when CF does not support tagged pointer string objects.
That breaks the test on platforms that don't support tagged pointer strings.
The test now does nothing if it does not get an NSTaggedPointerString back.

Our runtime doesn't fix up class field offset vectors for resilient ObjC base classes, causing the offsets to be wrong if the actual size of the base class differs from its compile-time claimed size. Use the ObjC runtime's ivar records instead if the class has ObjC heritage. We can't do this all the time because the ObjC ivar records aren't yet trustworthy for generic classes, but we don't fully support the mix of ObjC heritage and genericity very well anyway yet. Fixes <rdar://problem/17027510> in the short term.

This is our public API for how quicklooks work in the debugger, and the plan is to have this same API work in playgrounds as well

The <opaque> output is clearly useless, and annoying to see scattered around playgrounds
We don't have bandwidth right now to produce detailed useful reflection information, but at least show a basic understanding of data

Witness tables can't be dead-stripped without breaking the dynamic conformance queries printing now relies on. Fixes <rdar://problem/16993349>.
