This patch prevents writing ivar field for ObjC property whose type
is not trivially representable in ObjC within its DeclContext.
For example, in the case of the property `@objc var foo: String`,
it is accessed as an NSString on the ObjC side. Without this patch,
this property is backed with an ivar, to which direct accesses would
fail.

* [ClangImporter] Remove importer-based NS stripping.
As Tony puts it, in the end we wound up with more Foundation
declarations imported as members or keeping "NS" than those that
dropped it, and any further decisions will be made on a case-by-case
basis. Move all of the existing cases of prefix-stripping into
Foundation's API notes and drop the logic from the compiler.
Tested by dumping the generated interface for Foundation and its
submodules for both macOS and the iOS simulator, and comparing the
results. A few cases did slip through here because of the interaction
between "SwiftName" and "Availability: nonswift".
The next commit will re-add "NS" to some stragglers that we missed.

* APINotes: Add "NS" back to a few types.

* Remove now-redundant SwiftNames from API notes.
No change observed in the generated interface of Foundation and its
submodules.

This commit defines the ‘Any’ keyword, implements parsing for composing
types with an infix ‘&’, and provides a fixit to convert ‘protocol<>’
- Updated tests & stdlib for new composition syntax
- Provide errors when compositions used in inheritance.
Any is treated as a contextual keyword. The name ‘Any’
is used emit the empty composition type. We have to
stop user declaring top level types spelled ‘Any’ too.
We use Clang to produce Objective-C type encodings (e.g., for property
descriptors). In cases where we need to synthesize a Clang @interface
or @protocol to map a Swift type into a Clang type for this purpose,
attach an objc_runtime_name attribute to the synthesized Clang
declaration so that it gets the appropriate Objective-C runtime name
in the encoding, rather than simply falling back to the (unmangled)
Swift class or protocol name.
This requires a paired Clang commit, since Clang was ignoring the
objc_runtime_name attribute in its type encoding.

We were always mapping protocol and protocol-composition types to Objective-C ‘id’, which is incorrect. Instead, map down to ‘id’ (for AnyObject) or protocol-qualified ‘id’ (when there are other protocols).
Swift SVN r29407
When used in @objc protocol requirements, properties, or blocks, frameworks like JSCore expect the extended type encodings to accurately reflect the class of the parameters and returns. Fixes rdar://problem/19519390.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.
Swift SVN r24504
Refuse to load a module if it was compiled for a different architecture or
OS, or if its minimum deployment target is newer than the current target.
Additionally, provide the target triple as part of pre-loading validation
for clients who care (like LLDB).

Doing so is safe even though we have mock SDK. The include paths for
modules with the same name in the real and mock SDKs are different, and
the module files will be distinct (because they will have a different
hash).
This reduces test runtime on OS X by 30% and brings it under a minute on
a 16-core machine.
This also uncovered some problems with some tests -- even when run for
iOS configurations, some tests would still run with macosx triple. I
fixed the tests where I noticed this issue.

-enable-source-import doesn't play nice with debug info, and we want to be
able to run all tests with -g added. The last few tests that require
-enable-source-import could be built with --no-debug-info, or however we
end up spelling that.

Instead of hacking together inaccurate metadata only for object-typed properties, make an effort to produce accurate metadata for all types of properties, and accurately capture the "copy", "dynamic", and "weak" semantics of some properties. This is necessary for Core Data to accurately synthesize property accessors for non-object properties; currently it will generate bogus object accessors over properties with non-object type. <rdar://problem/17373368>
This isn't fully accurate, since Clang hides property type encoding behind a 'getObjCEncodingForPropertyDecl' that only accepts an ObjCPropertyDecl. With some refactoring, it should be possible to expose this.
