Fix an assertion which is triggered when the operands of a bitwise operator have different signedness.
This is done by promoting the operands to the largest bit width (taking sign/zero extension into account) and ignoring the signedness for the operation itself.
Addresses SR-1509 by adding a heuristic to import numeric literals with a
type cast. Two new cases have been added for macros with 4 or 5 tokens
to cover cases with or without sign tokens.
For the most part this was just "check isInstanceProperty"; the one feature not yet implemented
is the emission of ObjC metadata for class properties.

Per discussion, there are certain times where our APIs really want you to use
the performSelector family of methods (e.g. when the framework hands you a selector
and expects you to call it upon completion).
Although the methods still aren't type-safe, we are at least making the result
Unmanaged so that you're forced to think about whether it's +1 or +0 before you
use it, and so that the compiler doesn't accidentally try to retain a non-object
pointer.
This commit also removes the blocks on the makeObjectsPerformSelector... methods,
but Foundation plans to add NS_SWIFT_UNAVAILABLE there (see rdar://problem/21150180).

attribute or appear in a whitelist.
The initial whitelist is based on an audit I performed of our current
public SDKs. If there are CF types which appear only in our internal
SDKs, and somebody urgently needs to use them from Swift, they can
adopt the bridging attributes. The goal is to eventually eliminate
the whitelist and rely solely on bridging attributes anyway.
Sadly, CoreCooling was not included in my SDK audit and must be
explicitly annotated. :(
I've left the main database organized by framework, but I wanted
a quasi-lexicographically sorted version to permit efficient lookup.
We generate that copy automatically with gyb. I ended up having
to tweak handle_gyb_sources to allow it to drop the result in
CMAKE_CURRENT_BINARY_DIR instead of CMAKE_CURRENT_BINARY_DIR/{4,8}
if an architecture is not provided. I think this is abstractly
reasonable for generated includes, which have independent ability
to detect the target word size. But just between you and me,
I did it because I couldn't figure out how to add
"-I${CMAKE_CURRENT_BINARY_DIR/{4,8}" as a compile flag;
the obvious thing didn't work. Anyway, I'd appreciate it if
someone double-checked my cmake hackery here.

Previously we'd try to put the same method into the list of members multiple
times--once for each redeclaration in the @interface. This led to an
assertion failure.
Checking the canonical decl isn't super cheap, but the ObjCMethodDecl
redeclaration infrastructure seems to be fairly broken. We can revisit this
later.
There's also a test for what happens when categories get involved. I'm not
convinced this is correct behavior, either, and will file an additional bug
to look into that at some point.

This completes <rdar://problem/17024498>, except that we don't yet do
anything with 'deprecated' or 'obsoleted'. The former is covered by
<rdar://problem/17406050>, and I filed <rdar://problem/17873422> for the
latter.

Nearly all of them come from some annotation written explicitly in the
Objective-C header, and all of them should be shown in the generated
interface for an imported module.

...and 'assign' and 'unsafe_unretained' as 'unowned(unsafe)', if the
property is a class type.
This isn't important for the compiler, but it is documentation for users
when they look at the generated interface for an Objective-C module.
Note that this actually produces a decl users can't yet write:
unowned(unsafe) var foo: UIView!
That's <rdar://problem/17277899> unowned pointers can't be optional.

Because we don't want FooModule.#^A^# to show completion results for other
clang modules, global completion cache was replaced with a per-module cache.
