Array's getObjects:range: needs to fill the supplied buffer without
incrementing the reference count. For that reason, and to fulfill
lifetime expectations for Array elements that are computed
dynamically (e.g. from value types that are BridgedToObjectiveC), we
maintain a cache of converted objects associated with each Array.

Make CConstPointer<T> convertible from UnsafePointer<T>, inout T, and Array<T>, and nil; and make CMutablePointer<T> convertible from UnsafePointer<T>, inout T, inout Array<T>, and nil.

For container bridging, implement a '_bridge<T>' function that converts a Swift value to AnyObject using a runtime check for its _ObjCBridgeable conformance, crashing if one doesn't exist.

Think the scenarios through more carefully, create more reliable tests.
Fixes <rdar://problem/16105759> Too many retains for COW optimization
Swift SVN r14140
Define a "Mirror" protocol with methods for querying the number of children a structured value has, getting the name and mirror for each of those children, and a string and "IDE representation" of the value, as needed by playgrounds and by our planned generic printing facility.
In the runtime, define a "reflect" function that can provide a Mirror for any object, either using a "Reflectable" protocol conformance if available, or falling back to a magic implementation in the runtime that grovels the type metadata. Stub out a bare minimum default implementation.

Will serve as an IndexType for CollectionOfOne<T>
Open Question: should this become a full-fledged Int1 type, generated by
FixedPoint.gyb?
Swift SVN r13974
Mock up a naive Printable protocol, and do some dirty tricks in the runtime to implement a 'printAny' function that uses swift_conformsToProtocol to look up a conformance to Printable if the type has one, or falls back to a dumb opaque printing if it doesn't. Use this to make Array<T> Printable in some way or another for all T.

...which would of course prevent them from being used. Sadly, this includes
the one I just added, since I didn't actually test it against the original
project until now.
Add a regression test that all block shims have valid manglings without
any unmangled suffixes.
Swift SVN r12672
Because we're using a "brute-force" combination of conversion to
NSString and forwarding, this code will continue to work when String
is replaced by NewString. It may not be fast yet, but at least it
will flesh out the experience for Cocoa programmers
Swift SVN r11034
Add new builtins(by generalizing, renaming, and extending the builtins used for compile time integer literal checking). These new builtins truncate integers and check for overflow/truncation errors at runtime. Use these for FixedPoint conversion constructors.
Fix a routine in stdlib's String implementation and a test that relied on bitwise behavior of the constructors (and triggered overflows).
TODO:
- Teach CCP about these to get static checking.
- Add special builtins for same size signed <-> unsigned conversions.
Swift SVN r10432
Protocols with associated types can't currently be used as existential
types. Combined with the inability to create type constraints on
generic functions nested in generic types based on the outer type and
the inability to create closures of generic type and the inability to
create protocol constraints that require generic functions and the
inability to create protocols with init() requirements... and this is
what we get.
