These will be used for reflection, and eventually to speed up generic
operations on single payload enums as well.
Progress on <rdar://problem/21739870>.
Swift SVN r30214
Leave the qualification off of enum cases and type names when 'print'-ing them, but keep them on 'debugPrint'. (At least, at the outermost level; since ad-hoc printing of structs and tuples uses debugPrint, we'll still get qualification at depth, which kind of sucks but needs more invasive state management in print to make possible.) Implements rdar://problem/21788604.
Swift SVN r30166
We incorrectly tested the uninitialized "next" pointer against MAP_FAILED, instead of the real result of mmap. Fixes rdar://problem/21659505.
Swift SVN r30030
Change ProtocolConformanceRecord::getCanonicalTypeMetadata() to return null if
the class metadata in the protocol conformance record is null. This fixes a
runtime crash in swift_conformsToProtocol when there is a protocol extension of
a missing weakly-linked class.

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.
Swift SVN r30006
Metatypes can't directly conform to _ObjectiveCBridgeable, but we can pretend they do by making a struct with the same ABI conform and returning that conformance when we call findBridgeWitness on a metatype. Fixes rdar://problem/16238475.
Swift SVN r29999
The stdlib uses this condition to recognize types that represent classes without representation changing, which isn't true for metatypes. They will natively be pointers to the Swift type metadata instead of the ObjC class object, so a conversion step is necessary. This doesn't directly fix container bridging, but it prevents the runtime from trying to bridge verbatim metatypes without first changing them to ObjC representation.
Swift SVN r29998
Implement casting support for taking an AnyObject and conditionally converting it to a T.Type for some class type. Fix some memory management bugs too, where we used swift_release to release an object not known to have Swift refcounting. This mostly fixes rdar://problem/16238475, though the SIL optimizer still improperly folds away attempted casts from NSObject to a class metatype, and I haven't yet validated bridging support for NSArray<Class>*.
Swift SVN r29956
Revert "simd overlay: Use LLVM vector types."
This reverts commit r29922 and r29924.
More arm64 instruction selection errors.

Swift SVN r29891
Provide new swift_{alloc,dealloc,project}Box2 entry points that allocate, project, and deallocate typed boxes using runtime-instantiated metadata. Give these a new metadata kind, so that external tools recognize the difference and can interpret the metadata appropriately.
Swift SVN r29714
Implement these backstops in the stdlib instead of the runtime, where we can at least interpolate the error value and give a slightly more informative error. Could still be improved by handing the source location down from the point of the crash instead of using the location from the stdlib source. Somewhat addresses rdar://problem/20807523.
Swift SVN r29401
Our hack to generate a unique name by appending the class pointer doesn't produce a stable class name that can persist in NSKeyedArchiver, or eventually be used as a key for dynamic runtime instantiation. Generate a proper mangled name for the class instance by building a demangling AST from the metadata nodes and feeding it into the remangler. Should fix rdar://problem/18884563, though I need to try using an archiver with a generic class to verify.
Swift SVN r29316
armv7k can return 16-byte structs in registers, but the Swift side of
the reflection implementation assumes these structs return in memory.
Adding an intermediating struct for return values with an empty user
destructor guarantees that they come back in memory.

Swift SVN r29274
Move the check for NSError earlier so that it covers class cases, and put a check in _dynamicCastFromExistential to avoid the identical-class fast path when NSError's involved. Fixes rdar://problem/21116814.
Swift SVN r29130
This changes things like Swift.Dictionary<Swift.Int, Swift.AnyObject> to Dictionary<Int, AnyObject>
It has been suggested that playgrounds would benefit from not showing the fully qualified name.
Playgrounds use the runtime demangler to obtain type names, and honestly, I do not see enough value in those qualifiers being printed out to justify hackery in PlaygroundLogger or separate demangling logic
Swift SVN r28997
Previously a mirror for an empty case would have one entry, consisting
of the case name and a value of ().
Now, the mirror's summary shows both the type and the case. If there is
no payload, the mirror will not have any children. The presence of a
child indicates there is an actual payload.
Also put a non-ASCII character in the reflection test to ensure the
runtime's primitives can round-trip UTF8.
Fixes <rdar://problem/20994093>.
Swift SVN r28874
Now that we have lazy metadata accessors for classes and vtable thunking, we don't have any reason to prevent concrete subclasses of generic base classes. Wire up IRGen to lazily instantiate the superclass for concrete derived classes when their metadata is accessed, using a runtime function that installs all the necessary pointers and metadata and registers the fully-initialized class with the ObjC runtime.
Swift SVN r28520
This change attempts to introduce the functionality without being too
disruptive. After we branch, I want to consolidate some of the runtime
functions and implement this functionality for multi-payload enums
as well, which requires adding new runtime metadata.
Example:
(swift) enum Color { case Red, Green, Blue(Int) }
(swift) print(Color.Red)
REPL.Color.Red
(swift) print(Color.Blue(5))
REPL.Color.Blue(5)
Implements <rdar://problem/18334936>.
