The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.
Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.
Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.

The big changes are:
- Deleting Driver/(Arg|Opt)*
- Rewriting includes to llvm/Option/ and re-sorting
- 'using namespace llvm::opt' in clang::driver
- Fixing the autoconf build by adding option everywhere
As discussed in the review, this change includes using directives in
header files. I'll make follow up changes to remove those in favor of
name specifiers.

the various stakeholders bump up the reference count. In particular,
the diagnostics engine now keeps the DiagnosticOptions object alive.

This is similar to how we divide up the StaticAnalyzer libraries to separate
core functionality to what is clearly associated with Frontend actions.

express library-level dependencies within Clang.
This is no more verbose really, and plays nicer with the rest of the
CMake facilities. It should also have no change in functionality.

That commit added a new library just to hold the RawCommentList. I've
started a discussion on the commit thread about whether that is really
meritted -- it certainly doesn't seem necessary at this stage.
However, the immediate problem is that the AST library has a hard
dependency on the Comment library, but the dependencies were set up
completely backward. In addition to the layering violation, this had an
unfortunate effect if scattering the Comments library dependency
throughout the build system, but inconsistently so -- several parts of
the CMake dependencies were missing and only showed up due to transitive
deps or the fact that the target wasn't being built by tho bots.
It turns out that the Comments library can't (currently) be a well
formed layer *below* the AST library either, as it has an API that
accepts an ASTContext. That parameter is currently unused, so maybe that
was a mistake?
Anyways, it really seems like this is logically part of the AST --
that's the whole point of the ASTContext providing access to it as far
as I can tell -- so I've merged it into the AST library to solve the
immediate layering violation problems and remove some of the churn from
our library dependencies.

The member variable is always "LangOpts" and the member function is always "getLangOpts".

the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.
This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator. We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.

This fixes the FIXMEs in ParseAnalyzeArgs. (Also a
precursor to moving the analyzer into an AST plugin.)
For consistency, do the same with AssemblerInvocation.

a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation
objects created by ASTUnit were actually leaked. When I fixed that bug locally, it showed that a whole bunch of code assumed
that the LangOptions object that was part of CompilerInvocation was still alive. By making it heap-allocated and reference counted,
we can keep it around after the CompilerInvocation object goes away.
As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this
object may outlive the CompilerInvocation object.
This commit doesn't fix the CompilerInvocation leak itself. That will come when I commit the fix to llvm::RefCountedBase<T> to
mainline LLVM.

This is a new mode of migration, where we avoid modifying the original files but
we emit temporary files instead.
<path> will be used to keep migration process metadata. Currently the temporary files
that are produced are put in the system's temp directory but we can put them
in the <path> if is necessary.
Also introduce new ARC migration functions in libclang whose only purpose,
currently, is to accept <path> and provide pairs of original file/transformed file
to map from the originals to the files after transformations are applied.
Finally introduce the c-arcmt-test utility that exercises the new libclang functions,
update arcmt-test, and add tests for the whole process.
