Add new check: -check-objc-methodsigs. This check scans methods in

ObjCImplementationDecls and sees if a ancestor class defines a method with the
same selector but with a different type signature. Right now it just compares
return types, and mainly looks at differences in primitive values. The checking
will be expanded in the future.

Added AnalysisConsumer, a meta-level ASTConsumer class to drive various
...
analyses. This potentially is the primordial origins of a Clang-equivalent
"PassManager".
The new AnalysisConsumer interface allows multiple analyses to be run from a
single invocation of Clang.
Migrated the logic of "-warn-dead-stores" and "-warn-uninit-values" to use the
new AnalysisConsumer interface. The new interface results in a significant code
reduction to incorporate an analysis into the Driver.
Updated a test case to (correctly) acknowledge that it contains a dead store
(this check wasn't being performed because it was previously masked by
-warn-uninit-values).

'There's not much to say about this patch, it just adds the Arch Linux
gcc 4.3.1 header paths for i686 and amd64. The patch was generated
using "svn diff" with clang at revision 52660. The paths aren't
distribution-specific, so they should work for all Linux distributions
using the default(?) names like "i686-pc-linux-gnu".'

Added "InitializeTU" to ASTConsumer. This is used by Sema::ParseAST to pass a

TranslationUnit object instead of an ASTContext. By default it calls
Initialize(ASTConstext& Context) (to match with the current interface used by

to not free its Decls. This is a workaround for: <rdar://problem/5966749>

Fix <rdar://problem/5969777> clang ObjC rewriter: #imported file name mysteriously commented out
...
This fix involved tightening up needToScanForQualifiers(), which predated ObjCQualifiedIdType.
It also includes a minor tweak to the code that searches for the beginning of the qualified type. If the AST contained the correct beginning of the declaration (i.e. the beginning of the declaration specifiers), this code would be more robust. Since it doesn't, we apply an adhoc heuristic. Note that DeclSpec contains this info...we just don't propagate it to the AST (at present).
