Equivalent to llvm::sys::fs::rename, except that if the destination file
exists and has the same contents as the source file, the source file is
simply deleted and the destination file is not touched.
Used in next commit.

Replace ReST-flavored documentation comments with Markdown.
rdar://problem/20180412
In addition to full Markdown support, the following extensions are
supported. These appear as lists at the top level of the comment's
"document". All of these extensions are matched without regard to
case.
Parameter Outlines
------------------
- Parameters:
- x: ...
- y: ...
Separate Parameters
-------------------
- parameter x: ...
- parameter y: ...
- Note:
Parameter documentation may be broken up across the entire comment,
with a mix of parameter documentation kinds - they'll be consolidated
in the end.
Returns
-------
- returns: ...
The following extensions are also list items at the top level, which
will also appear in Xcode QuickHelp as first-class citizens:
- Attention: ...
- Author: ...
- Authors: ...
- Bug: ...
- Complexity: ...
- Copyright: ...
- Date: ...
- Experiment: ...
- Important: ...
- Invariant: ...
- Note: ...
- Postcondition: ...
- Precondition: ...
- Remark: ...
- Remarks: ...
- See: ...
- Since: ...
- Todo: ...
- Version: ...
- Warning: ...
These match most of the extra fields in Doxygen, plus a few more per request.
Other changes
-------------
- Remove use of rawHTML for all markup AST nodes except for those
not representable by the Xcode QuickHelp XSLT - <h>, <hr/>, and of
course inline/block HTML itself.
- Update the doc comment RNG schema to more accurately reflect Xcode
QuickHelp.
- Clean up cmark CMake configuration.
- Rename "FullComment" to "DocComment"
- Update the Swift Standard Documentation (in a follow-up commit)
- Update SourceKit for minor changes and link against cmark
(in a follow-up commit).

@objc protocols aren't supported with an ObjC runtime, but we still want values of AnyObject type to be word-sized. Handle this by turning the binary "needsWitnessTable" condition into a "dispatch strategy" enum, so we can recognize the condition "has no methods, so neither swift nor objc dispatch" as distinct from either swift or ObjC protocol representations. Assign this dispatch strategy when we lower AnyObject. Should be NFC for the ObjC-enabled build.
(It would also be beneficial for the ObjC-runtime-enabled version of Swift if AnyObject weren't an @objc protocol; that would mean we could give it a canonical protocol descriptor in the standard library, among other things. There are fairly deep assumptions in Sema that AnyObject is @objc, though, and it's not worth disturbing those assumptions right now.)
Reapplying with updates to the runtime unit tests.

This library becomes a permanent interface that we would need to support
in the long term, so we should get dylib names and APIs right.

...and rename it to swift_common_llvm_config.
This is the function that acts like llvm_config but handles the LLVM build
being a different configuration from the Swift (or SourceKit) build, which
can be problematic for multi-configuration build schemes like Xcode.
There's also one fix here: LLVM dependencies for dylibs weren't being
properly added. (This is the "SHARED_LIBRARY" case near the bottom.)

These should all apply to any Darwin platform, and the current behaviour
was breaking cross-compilation.
Introduces a SWIFT_DARWIN_VARIANTS pattern, to be used as follows:
if(SWIFT_HOST_VARIANT MATCHES "${SWIFT_DARWIN_VARIANTS}")
Also fix one place where I checked the CMAKE_SYSTEM_NAME instead of the
host variant that I recently introduced. I haven't attempted to find
the rest of the places we're doing this though.

If an existential type for a special protocol (not a composition) is instantiated, carry the special protocol identifier from that protocol to the existential, allowing us to easily recognize existentials with unique runtime characteristics.
Swift SVN r26436
- Add frontend and standard library build support for tvOS.
- Add frontend support for watchOS.
watchOS standard library builds are still disabled during SDK bring-up.
To build for TVOS, specify --tvos to build-script.
To build for watchOS, specify --watchos to build-script (not yet supported).
This patch does not include turning on full tests for TVOS or watchOS, and
will be included in a follow-up patch.
Swift SVN r26278
We can't do this because the object was deallocated. However, ASan should flag us if we regress on touching deallocated unowned-referenced objects though, so we don't need this. rdar://problem/19677703
Swift SVN r24894
ObjC unowned references are backed by an ObjC weak reference which will eagerly deallocate the object when it's strongly released, so in an unknown-refcount situation, we can't safely dereference the object pointer to determine its Swiftness. We can, however, look at the side table of weak references; if there's an entry for this object, then it's reliably an ObjC object (or it's some other object that got allocated in the reclaimed space for the dead object, but that's a race we fundamentally can't win with this broken design). Fixes rdar://problem/18091547 (modulo the aforementioned reallocation race).
Swift SVN r24825
Instead of directly referencing a long-dead constructor from the standard library, put a purpose-built function in StdlibUnittest to feed a Swift object reference to the test C code. rdar://problem/18498737
Swift SVN r24816
clang-600 doesn't consider explicit conversion operators as satisfying
std::is_constructible, even though actually writing the construction
does work. Just don't run that part of the test if that's how
std::is_constructible behaves.
Swift SVN r24603
We don't actually check them yet, but this fits them into the same dependency
structure as intra-module dependencies.
Part of rdar://problem/19270920
Swift SVN r24335
(and similar mixed modes)
This is duplicating some of the work in swift_llvm_config, and should
probably be refactored back there at some point, but for now this gets
unit tests building in Xcode when the build configurations for LLVM and
Swift aren't the same.
