Make the "merging class-wide information into method information"
operation part of ObjCMethodInfo. It doesn't belong in the Clang
importer.

Now that bridging headers from ASTs are always present and bridging headers
from the command line are checked in advance, we no longer need to worry
about the Clang instance failing to find the bridging header. That's good,
because this wasn't implemented correctly anyway: if a bridging header
imported a module, we could get an error.
Swift SVN r20129
We do this so that the swiftmodule file contains all info necessary to
reconstruct the AST for debugging purposes. If the swiftmodule file is copied
into a dSYM bundle, it can (in theory) be used to debug a built app months
later. The header is processed with -frewrite-includes so that it includes
any non-modular content; the user will not have to recreate their project
structure and header maps to reload the AST.
There is some extra complexity here: a target with a bridging header
(such as a unit test target) may depend on another target with a bridging
header (such as an app target). This is a rare case, but one we'd like to
still keep working. However, if both bridging headers import some common.h,
we have a problem, because -frewrite-includes will lose the once-ness
of #import. Therefore, we /also/ store the path, size, and mtime of a
bridging header in the swiftmodule, and prefer to use a regular parse from
the original file if it can be located and hasn't been changed.

We're not using this for anything, yet, so there aren't any checked-in
tests. Also note that I'm using ".apinotesc" for the binary form of
API notes.

This is a hack to work around two issues:
- <iso646.h>, which defines macros for "and", "or", and "not" (among other
things) is an implicit submodule of Darwin.
- Macros even in explicit submodules are leaking out when the parent module
is imported <rdar://problem/14870036>.
There's no actual reason to require <iso646.h> in SDK header files -- it
should be a user-level choice whether or not to use those names. And
selectors with "and", "or", and "not" in them should not be mangled by this.
So, as a hack, we define the header guards that <iso646.h> uses ahead of
time, so that the file will be ignored. We do this for /both/ variants of
<iso646.h> on our system (Clang's and /usr/include's) just to be safe.

Because extensions don't have any identity we can check against, we can't
tell when we see an Objective-C category if it came from a Swift extension.
Change PrintAsObjC to mark all such categories with SWIFT_EXTENSION, and
just skip them unilaterally when importing Objective-C code.
Also, actually give Swift extensions a name when writing them as Objective-C
categories. Previously, they were nameless categories ("class extensions"),
but methods in a class extension are supposed to be implemented in the class's
main @implementation, so people were getting unexpected warnings about missing
implementations.

Add the ability to store optionality of the ObjC method parameters and return
type in a sidecar. This hardcoded info is then used to import Objective C
object pointer types as either optional or none, instead of implicitly
unwrapped optionals.
The feature is enabled with -import-with-tighter-objc-types=true.

.../if/ the protocol and the class are from the same top-level Clang module.
If not, the protocol is /not/ renamed, and users will have to disambiguate
with module qualification.
This kills our hardcoded "RenamedProtocols" list; it turns out this pattern
is more common than we thought /and/ leads to cross-referencing issues.

Until we can build against LLVM and Clang master completely, we should hold
off on any changes that take us out of sync with the wwdc-master tags.

This is -Werror=non-modular-include-in-framework-module for Clang, and
prevents the same content from being treated as part of two different
modules. It's mostly just a sanity check to keep from having problems later.

Use this for -class and +class, to make them less ad hoc. More to follow.
As part of this, actually mark imported unavailable declarations in a
protocol as "optional", because nobody should have to implement an
unavailable declaration.

We still have an outstanding incompatibility with LLVM trunk, so let's
just get in a state where we can build against known commits for now.

...so don't report a second "module missing" error from Swift itself.
We do still treat the Clang module failing to build as a fatal error.

We're not mapping source locations over correctly yet, so the file name
where an error occurs gets shoved into the diagnostic text, but that's
fine for now.
This also silences the "module 'Blah' not found" error coming from the
importer whenever Swift itself can be responsible for importing the module.
Still to do: if we can't build a Clang module, we shouldn't report that
error and then say it can't be found.

This allows "obj.description!" to work on iOS when 'obj' is an AnyObject,
even though 'description' is an implicit property created by the importer.

attributes and create implicit conversions for them.
Also, when generating Clang modules for import, set the
appropriate macro to make CoreFoundation actually apply
those attributes to its typedefs.
Also, give shared linkage to imported class method
definitions.
The net effect is that CFString now automatically
converts to NSString and vice-versa.
Depends on Clang r208756 in order to preserve attributes
applied to tag types in multiple typedef declarations.
Swift SVN r18069
This performs very conservative dependency generation for each compile task
within a full compilation. Any source file, swiftmodule, or Objective-C
header file that is /touched/ gets added to the dependencies list, which
is written out on a per-input basis at the end of compilation.
This does /not/ handle dependencies for the aggregated swiftmodule, swiftdoc,
generated header, or linked binary. This is just the minimum needed to get
Xcode to recognize what needs to be rebuilt when a header or Swift source
file changes. We can revisit this later.
This finishes <rdar://problem/14899639> for now.

Previously, we were just using the base name, which resulted in massive
inefficiency when dealing with Clang (we basically had to check every
selector in the system to see if it had the same first selector piece).
I've hacked ConstraintSystem a bit to carry a map from UnresolvedDotExpr
to the ApplyExpr that consumes it, so that we can use the full DeclName
and look up methods by full selector.
Now that dynamic lookup is fast, re-enable it for the
Foundation_bridge.swift test. (r17520 actually provided most of the benefit.)
This does break selector lookup on AnyObject when doing selector splitting,
and slightly regresses diagnostics when you try to call a method on AnyObject
and forget a parameter name.
<rdar://problem/16808651>. Part of the Playground performance efforts.
Swift SVN r17524
This improves the -import-objc-header option to read decls from the header
as well. Any declaration that is not from a module will be considered to be
part of the "header module". Conversely, forward-declarations appearing in
the header will be resolved by looking through all modules responsible for
importing a header.
