Extend clang_getCursor() to take a 'relativeDecl' argument (so speed up searching). Without a 'relativeDecl', the algorithm is n-squared. For example, running the following command on 'Large.m' takes hours without a 'relatvieDecl'.

Add destructor and cleanup code to LocationContext (fixing some leaks). Along the way, have
AnalysisManager periodically cleanup its AnalysisContextManager and LocationContextManager objects,
as they don't need to forever retain all the CFGs ever created when analyzing a file.

- Extend clang_createIndex() to support PCH and diagnostic 'filtering'. This seems cleaner to me without sacrificing much flexibility.
- Remove clang_wantOnlyLocalDeclarations().
- Remove 'displayDiagnostics' arguments to clang_createTranslationUnitFromSourceFile() and clang_createTranslationUnit().
- Have clang_createTranslationUnitFromSourceFile() strip the '-o <outfile>' command line arguments if they exist. Document this semantic in the header. Also verify we have a valid ASTUnit before telling it to 'unlinkTemporaryFile()'.

Remove default argument for ImpCastExprToType. Add appropriate argument
to all callers. Switch a few other users of CK_Unknown to proper cast
kinds.
Note that there are still some situations where we end up with
CK_Unknown; they're pretty easy to find with grep. There
are still a few missing conversion kinds, specifically
pointer/int/float->bool and the various combinations of real/complex
float/int->real/complex float/int.

Call 'clear()' in ~RopePieceBTreeLeaf(), decrementing the reference

Really fix <rdar://problem/7312058> by adding a 'displayDiagnostics' option to
clang_createTranslationUnit() and clang_createTranslationUnitFromSourceFile(). The user can now
specify if the diagnostics from Clang are printed to stderr or are silenced completely. We can
obviously evolve this API to be more general in the future.
Note: Added a FIXME since I wasn't certain what was the best way to redirect to something analogous
to '/dev/null' on Windows.

The constructor for ASTUnit now takes a DiagnosticClient*, allowing uses of ASTUnit to specify
alternate DiagnosticClients. To match this API, ASTUnit::LoadFromPCHFile() now takes a corresponding
DiagnosticClient* argument as well. The DiagnosticClient object is destroyed when the ASTUnit object
is destroyed.
The CIndex library now uses this API to create a 'IgnoreDiagnosticsClient' that simply silences
diagnostics when using the clang_createTranslationUnitFromSourceFile() function. This fixes
<rdar://problem/7312058>. This API can change in the future as we add more flexibility for clients.
