This helps array append's performance by ~ 2x. The generic max with a variadic
argument takes at least 3 arguments, it creates a temporary array then iterates
over the array.
This is an updated version of r18764.

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.

We should have thought about this option earlier. This fixes:

This patch allows people to define a func quickLookObject() that returns an NSString, and have the playgrounds pick that up for the sidebar

so I took the liberty to 'privatize' them with a leading underscore.
This also completely removes '_ArrayBody' from the public interface.
Should be NFC, apart from the public interface change.

-Hide vars that have a private type.
-Hide functions that have a parameter with private type or a parameter name with leading underscore.
-Minor change in StringUTF16.swift to avoid printing "func generate() -> IndexingGenerator<_StringCore>".

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

XCTest needs a way to get the demangled name of a test case class,
so provide one by overriding NSObject.className.
Addresses <rdar://problem/17010812>.

Before this change, the dispatching hacks sent convertFromArrayLiteral
through the "Sequence" path, wherein we could not assume the ability to
non-destructively measure the length of the Sequence before beginning to
add the elements, which resulted in buffer reallocations as elements
were added. Now we the sequence is measured and storage is
pre-allocated.

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.

size; don't actually enable the assertion yet, though.
