ArraySlice indices now map directly onto the collection it is slicing
and maintains that mapping even after mutations.
Before:
var a = Array(0..<10)
var s = a[5..<10]
s.indices // 0..<5
s[0] = 111
s // [111, 6, 7, 8, 9]
s.removeFirst()
s.indices // 1..<5
After:
var a = Array(0..<10)
var s = a[5..<10]
s.indices // 5..<10
s[5] = 99
s // [99, 6, 7, 8, 9]
s.removeFirst()
s.indices // 6..<10
- Refactor some of the internals of the buffer types to make it easier
to read and understand.
- Add Array, ArraySlice, and ContiguousArray to the test suite at the
RangeReplaceable test entry points, subjecting them to the same tests
as all of our collections.
- Update existing test expectations for the indexing changes.

These types are leftovers from the early pre-1.0 times when Int and UInt
were always 64-bit on all platforms. They serve no useful purpose
today. Int and UInt are defined to be word-sized and should be used
instead.

There is no reason for the compiler to be synthesizing a body of
_domain when it can be implemented in a protocol extension. As part of
this, fix a recent regression in the computed domain: it was using
string interpolation, which means that the recent changes not to print
qualified names affected the domain of the generated NSErrors. Oops.

In iOS 9 and OS X 10.11 the old GameKit was effectively renamed GameCenter, while
the new GameKit is a sort of umbrella framework like Cocoa. We need to support
backwards deployment, though, so the GameCenter overlay links to GameKit.framework.
(This is essentially the same solution implemented for CoreImage moving out of
QuartzCore in r28449)

Due to the fact that AnyClass is not Hashable, and that currently
NSKeyedArchiver/Unarchiver work with NSObject-derived, NSCoding
compliant classes, we are marking the decodeObjectOfClasses API refined
for Swift in our objc header and providing the desired overlay in our
overlay as shown below.
Arrays were also considered (for both API), but the underlying
implementation is entirely set-based, and using Arrays in Swift vs Sets
in objective C felt like too far a deviation.

Changes to the Dictionary test are caused by bumping the Fonudation API
epoch and taking in a fix in the types used in an NSDictionary
initializer.

Class representation
As Joe explained, when Swift passes a metatype like AnyClass for an type
defined in Objective-C, it will pass the Swift metadata pointer instead
of an id-compatible Class.

AppKit links CoreData and this relationship isn't expressed
in the build mechanics for the overlays, which can cause
link failures when building the overlay.

This does not cause any functionality change, except it solves the issue I was running into last night where an array of NSString-s would expose its child values as plain Strings

Per Dmitri's request and stdlib conventions. Also, remove the reference to
what's now '_value' from the DarwinBoolean tests, and use unsafeBitCast
instead to mimic representation-compatible access from C.

These are contexts where we have enough information to bridge /back/
properly; that is, where we can distinguish CBool, ObjCBool, and
DarwinBoolean. In cases where we can't, we keep the three separate;
only CBool is really the same type as Bool.
This also affects current import behavior for ObjCBool, which was previously
incorrectly conflated with CBool in certain cases.

Like ObjCBool is a legitimate boolean type rather than a typealias for Int8,
DarwinBoolean is better than a typealias for UInt8. It's a BooleanType
(meaning you can use it directly in if/while/?:) and BooleanLiteralConvertible
(meaning you can use 'true' and 'false').
The next commit goes even further, so that you only have to deal with
DarwinBoolean when ABI is important. At all other times it should be
bridged with Bool, just like ObjCBool.

Checked arithmetic is probably not what you want from the vector unit, but we still want code to be explicit about the fact that it's using wrapping semantics instead of trapping or UB semantics. Provide the wrapping variations of the operators, and leave behind unavailable definitions to direct users to the wrapping operations if they try to use the standard ones.

This brings the David Owens benchmark from http://owensd.io/2015/06/27/performance-xcode7-beta-2.html from parity with simd.h-based C to 3x faster.
Before:
RenderGradient ([UInt32].withUnsafeMutablePointer (SIMD)) │ 7.035851 │ 6.304739 │ 9.815832 │ 1.212 │

This also addresses rdar://problem/21574425, since Builtin.add_VecNxIntM isn't overflow-checked, and overflow checks really aren't wanted when working with vector types directly.
Reapplying now that Nadav's fixed the ARM64 SelectionDAG issue this exposed before, and Arnold's fixed
yet another SelectionDAG issue exposed after that.
