We were missing -_tryRetain, -_isDeallocating, -allowsWeakReference and -retainWeakReference implementations on SwiftObject, so forming an ObjC weak reference to a pure Swift object always failed and produced a nil reference. Fixes rdar://problem/18637774.

The name was not only long and unwieldy, but inconsistent with our
conscious decision to avoid the use of "elements" in APIs as mostly
redundant.

This fails iOS buildbot because UIColor and NSColor disagree on the
initializer's optionality. Backing out the audit decision while
investigating the solution.
Swift SVN r22192
Per API review with Ali. While we're here, give the initializer a corresponding 'rawValue' argument label, and change the associated type name to RawValue to match.
Swift SVN r21888
Eliminate the implicit conversion from NSNumber to one of its bridged
value types (Int, Float, Double, Bool, etc.). One can use "as" to
perform the conversion instead. This eliminates a class of
accepts-dubious that involve lossy conversions from NSNumber to Int.
Our eventual arc is to eliminate all of these conversions. This is a
small, high-value step along that path rdar://problem/18269449.

Redefine the RawRepresentable protocol to use an 'init?' method instead of 'fromRaw(Raw)', and a 'raw' get-only property instead of 'toRaw()'. Update the compiler to support deriving conformances for enums and option sets with the new protocol. rdar://problem/18216832

Nor is ConstFSEventStreamRef.
Unfortunately, they both get bridged to COpaquePointer, so they're not
constructible from one another--they're identical.

Swift SVN r21546
The syntax being reverted added busywork and noise to the common case
where you want to say "I have the right address, but the wrong type,"
without adding any real safety.
Also it eliminated the ability to write UnsafePointer<T>(otherPointer),
without adding ".self" to T. Overall, it was not a win.
This reverts commits r21324 and r21342

This takes all %target-run-simple-swift and %target-run-stdlib-swift
invocations and runs them using the interpreter instead. To enable this
mode, pass --param=interpret to lit.py; you can add this flag to the
LLVM_LIT_ARGS CMake setting (which defaults to "-sv").
This doesn't support separated %target-build / %target-run steps, nor
does it work with StdlibUnittest (which uses posix_spawn to run its
subtasks). But it's a start.

We don't want typos in import statements to take down the whole REPL, but we
/do/ want the REPL to be honoring fatal errors that effectively take down the
ASTContext.
This doesn't (yet) apply to the real LLDB REPL, which does not use
SourceFileKind::REPL for its input. The right option to test there is
LangOpts.DebuggerSupport, but that's currently being set for Playgrounds as
well. I've filed <rdar://problem/18090611> for LLDB to adjust their input.

This regresses a bit on the diagnostic when a submodule is missing, as well
as missing out on Clang's automatic typo correction, but it does avoid putting
the Clang CompilerInstance into an error state, which is important for the
REPL. It's also not entirely clear that Clang had the right behavior in this
case either---we'd get a module back, but if the particular submodule we
asked for didn't exist we might get its parent. We can revisit this later.
Prerequisite for <rdar://problem/17994094>.

Previously, it was possible to write Unsafe[Mutable]Pointer(x) and have
Swift deduce the pointee type based on context. Since reinterpreting
memory is a fundamentally type-unsafe operation, it's better to be
explicit about conversions from Unsafe[Mutable]Pointer<T> to
Unsafe[Mutable]Pointer<U>. This change is consistent with the move from
reinterpretCast(x) to unsafeBitCast(x, T.self).
Also, we've encoded the operations of explicitly adding or removing
mutability as properties, so that adding mutability can be separated
from wild reinterpretCast'ing, a much more severe form of unsafety.
Swift SVN r21324
Now that CGFloat is its own distinct type, it's useful to have Double
initializers to go along with the Int initializers we added a while
back <rdar://problem/17224725>.

This function mixes the bits in the hash value, which improves Dictionary

Regressions are in benchmarks that use `Int` as dictionary key: we are just
doing more work than previously (hashing an `Int` was an identity function).

The test harness now can recover after test crashes, allowing:
- check for crashes themselves (without reporting them to the Python lit driver,
which is about 10x slower -- even if CrashTracer is disabled);
- recover from unexpected test crashes and run the rest of the tests;
- this lays the groundwork for assertions that end the test execution, but
allow the rest of the tests to run (rdar://17906801).
Note that we don't spawn a fresh process for every test. We create a child
process and reuse it until it crashes.

This handles things like NSSwapHostLongLongToBig and MKMapRectMake that
are static inline functions that themselves call other static inline
functions.

This requires a bit of special handling because we override the getter's type
in the importer, to make sure it's compatible with the setter, but other than
that we just use the information from the apinotes file.

This allows us to switch on an optional value and match it to concrete
values without explicitly writing the ".Some"'s. Better testing to follow...
Swift SVN r21018
We now allow switches like this:
switch anyObject {
case let str as String: // bridged via NSString
println(str)
case let intArr as [Int]: // bridged via NSArray
println(intArr)
default:
}
Note that we do not allow collection downcasting in switch statements
(yet); that's covered by <rdar://problem/17897378>.
Swift SVN r20976
This allows one to cast a value type (say, [String]) to AnyObject or
NSCoding, for example. It's another piece of <rdar://problem/17637959>.
