92a524fd47 Experimental stab at using relexing to identify preprocessor 
directives while annotating tokens in CIndex. This functionality
should probably be factored out of this routine, but we're not there
yet.

802b77601e Introduce a new BufferResult class to act as the return type of 
SourceManager's getBuffer() (and similar) operations. This abstract
can be used to force callers to cope with errors in getBuffer(), such
as missing files and changed files. Fix a bunch of callers to use the
new interface.

Add some very basic checks for file consistency (file size,
modification time) into ContentCache::getBuffer(), although these
checks don't help much until we've updated the main callers (e.g.,
SourceManager::getSpelling()).

89a56c561f When given unsaved files in clang_createTranslationUnitFromSourceFile, 
copy the source buffers provided rather than referencing them
directly, so that the caller can free those buffers immediately after
calling clang_createTranslationUnitFromSourceFile(). Otherwise, we
risk hitting those buffers later (when building source ranges, forming
diagnostics, etc.).

0e2930979d Change cursor behavior for attributes to have them visited as part of recursing

33cdd81064 Rework how CIndex handles diagnostics. Rather than using a callback, 
we attach diagnostics to translation units and code-completion
results, so they can be queried at any time.

To facilitate this, the new StoredDiagnostic class stores a diagnostic
in a serializable/deserializable form, and ASTUnit knows how to
capture diagnostics in this stored form. CIndex's CXDiagnostic is a
thin wrapper around StoredDiagnostic, providing a C interface to
stored or de-serialized diagnostics.

I've XFAIL'd one test case temporarily, because currently we end up
storing diagnostics in an ASTUnit that's never returned to the user
(because it contains errors). I'll introduce a temporary fix for this
soon; the real fix will be to allow us to return and query invalid ASTs.

5cca6ebae9 Move createCXString() functions out of CIndexer and into the clang::cxstring namespace. 
We can much more succinctly refer to these functions this way.

Also change the default behavior of createCXString(StringRef&) to duplicate the
string.  This is almost always what we want.  The other case is where we pass
a constant c-string, which uses the other version of createCXString().

474b207716 CIndex: Stop hiding magic end bit in CXSourceRange locations where clients can't 
see it. Instead, translate the locations up-front when we create a

 - This is part of a move to make CXSourceRange a pure half-open range, which is
   a more natural API for clients to deal with. More cleanups to follow.
