Fariborz Jahanian 48fd81b484 objc-arc: introduce -no-finalize-removal which in gc mode,
leaves "finalize' behind and in arc mode, does not
include it. This allows the migrated source to be compiled
in both gc and arc mode. // rdar://10532441

Fariborz Jahanian aa7b9aa10d arc migrator: Provide infrastructure to add options
specific to migrator. Use its first option to
warn migrating from GC to arc when 
NSAllocateCollectable/NSReallocateCollectable is used.

Douglas Gregor 32fbe31246 Extract the (InputKind, std::string) pair used to describe inputs to
the front end into its own class, FrontendInputFile, to make it easier
to introduce new per-input data. No functionality change.

Ted Kremenek 2acedbd417 Refine placement of LangOptions object in CompilerInvocation by adding a new baseclass CompilerInvocationBase with a custom copy constructor. This ensures that whenever the CompilerInvocation object's copy constructor is used we always clone the LangOptions object.

Ted Kremenek 8cf47df72f Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted object. I discovered that llvm::RefCountedBase<T> has
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.

Douglas Gregor d0e9e3a6a5 Introduce a pure virtual clone() method to DiagnosticConsumer, so that
we have the ability to create a new, distict diagnostic consumer when
we go off and build a module. This avoids the currently horribleness
where the same diagnostic consumer sees diagnostics for multiple
translation units (and multiple SourceManagers!) causing all sorts of havok.

Argyrios Kyrtzidis d571363e45 [arcmt] Add some additional driver flags to optionally emit or save the pre-migration ARC errors.

Argyrios Kyrtzidis 7fbd97f641 [arcmt] Introduce new '-ccc-arcmt-migrate <path>' ARC migration driver option.
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.

John McCall 24fc0decfe Change the driver's logic about Objective-C runtimes: abstract out a
structure to hold inferred information, then propagate each invididual
bit down to -cc1.  Separate the bits of "supports weak" and "has a native
ARC runtime";  make the latter a CodeGenOption.

The tool chain is still driving this decision, because it's the place that
has the required deployment target information on Darwin, but at least it's
better-factored now.
