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>.

If we were deleting a key in the middle of a collision chain, and the tail of
the collision chain had keys whose ideal bucket was located before the hole
that we just created, we would mistakenly not relocate those keys.

There's a bit of a reshuffle of the ExplicitCastExpr subclasses:
- The existing ConditionalCheckedCastExpr expression node now represents
"as?".
- A new ForcedCheckedCastExpr node represents "as" when it is a
downcast.
- CoerceExpr represents "as" when it is a coercion.
- A new UnresolvedCheckedCastExpr node describes "as" before it has
been type-checked down to ForcedCheckedCastExpr or CoerceExpr. This
wasn't a strictly necessary change, but it helps us detangle what's
going on.
There are a few new diagnostics to help users avoid getting bitten by
as/as? mistakes:
- Custom errors when a forced downcast (as) is used as the operand
of postfix '!' or '?', with Fix-Its to remove the '!' or make the
downcast conditional (with as?), respectively.
- A warning when a forced downcast is injected into an optional,
with a suggestion to use a conditional downcast.
- A new error when the postfix '!' is used for a contextual
downcast, with a Fix-It to replace it with "as T" with the
contextual type T.
Lots of test updates, none of which felt like regressions. The new
tests are in test/expr/cast/optionals.swift.

Many changes in how we're presenting the NSString APIs on String, most
notably that we now traffic in String.Index and Range<String.Index>
rather than Int and NSRange. Also we present NSString initializers that
can fail only as factory functions, and factory functions that can't
fail only as init functions.
About 25% of the API changes here have been reviewd by the Foundation
guys, and testing is, as it has always been, admittedly spotty. Dmitri
is going to be writing some more comprehensive tests.

not an alignment value.
Assert that various entrypoints get an alignment mask.
Get everything uniformly passing an assertion about
dealloating an object with the correct allocation
size; don't actually enable the assertion yet, though.

- rdar://problem/16776273, wherein conversions between nil and .None were permitted
due to an implicit conversion between nil and COpaquePointer.
- rdar://problem/16877526, where we needed to add new equality overloads to handle
conversions between nil and .None given the supression of user conversions.
(Some minor tweaks this time around for better interoperability with AnyObject.)

UIViewController is able to find nib files that have names derived from the
UIViewController subclass's name. This change modifies UIViewController's
lookup so it is able to find nib files for Swift class names.

Dictionary's isBridgedToObjectiveC() was overly restrictive. This went
unnoticed because the tests were using internal Dictionary APIs to construct
the desired state, instead of going thourgh casts.
