This is the most general dynamic cast operation, permitting
arbitary source and destination types and handling arbitrary
changes in representation. A value of the destination type
is constructed in an address provided by the caller; flags
control the behavior w.r.t. the source value.
Not yet used; probably buggy in various particulars.

Don't use spare bits on platforms that use ObjC tagged pointers when an enum payload involves a class-constrained existential, archetype, or ObjC-defined class type. If a payload is of a Swift-defined class type, we can still assume it's a real pointer and use its spare bits. Add an @unsafe_no_objc_tagged_pointer attribute that can be applied to protocols to denote that existentials bounded by that protocol can use spare bits; this is necessary to preserve the layout of bridged Array and Dictionary types, which should not be bound to tagged pointer types in practice (fingers crossed). Fixes <rdar://problem/16270219>.

put the result in a different place.
WIP: no IRGen support yet.
This will eventually be the required form when casting
to an address-only type; the existing instructions will
have only scalar outputs.

dynamicCastClass assumes that the destination type is a
Swift class type.
dynamicCastObjCClass assumes that the destination type is
an ObjC class type (represented as ObjC metadata, not type
metadata).
dynamicCastUnknownClass assumes only that the destination
type is some kind of class.

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
