Added a workaround for <rdar://problem/16953026> that allows them to
pass and flipped the sense of a test that was failing because we can now
downcast an Array that we couldn't downcast before.

conform to LogicValue.
This approach was taken to keep _isNull because I first tried
to just use comparisons to nil instead of isNull(). Apparently
that led to some circular definitions, so it was easier to just
stage it this way.

Sorry for the number of reverts, but I needed to do this many to get a clean

One of my recent type-checker changes starting passing all array
upcasts, including "bridged" ones like String[] -> AnyObject[],
through the library entry point _arrayUpCast, which is only meant for
class/ObjC existential types that are bridged verbatim.
Fixes part of <rdar://problem/16952238>; more cleanup to follow.

The new sugar is 'NSErrorPointer', which hides 'AutoreleasingUnsafePointer<NSError?>'.
I have not yet tested this on iOS, which previously had problems
with the type sugar import. I'll try and test that now.

The runtime implementation of 'as T' freaks out in cases involving protocols. This is an expedient workaround that fixes <rdar://problem/16950035>.
Swift SVN r18263
When an NSArray is force-downcast to T[] at an API boundary, we need to
remember that each element needs to be dynamically checked when
accessed. No deferred casts are being generated yet, so NFC

Turns out we really want to use reinterpretCast when we know it will
work, rather than a checked downcast + forced optional unwrapping. The
latter will only be as fast as the former in -Ofast
Swift SVN r18241
This not only removes some code, but should allow more optimization and
inlining in the common case where the Swift type is a class or @objc
existential such as AnyObject

I personally like ~(cast)0, but (cast)-1 felt more consistent with LLVM
style; and the waffling before finishing my coffee this morning made the
code wrong. Whoops.
