The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches.

This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic.

By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. 

Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks.

over the types of MemRegions. This allows the compiler to warn us which regions
are not handled, and also is a little faster.

CodeTextRegions can only be casted to FunctionPointer or BlockPointerTypes. This
simply isn't true. We can handle bogus operations on CodeTextRegions (e.g, an
array access) elsewhere.

void**, void***, etc.  Such casts should just pass the region through.

Rename potentially ambiguous member template 'getRegion' to 'getSubRegion' to hopefully resolve template lookup ambiguities on some compilers.

and replace the 'clang-cc' option '-analyzer-store=basic-new-cast' with
'-analyzer-store=basic-old-cast'. We'll keep the old CastRegion implementation
around for a little while for regression testing.

Add test for C++ [over.over.]p1, the contexts in which one can take the address of an overloaded function.

Store the isAddressOfOperand in the UnresolvedDeclRefExpr, so that we can pass it when instantiating the expr. Fixes another member pointer bug.

address of an overloaded function (which may involve both functions
and function templates).

It's not allowed to form member pointers to members that have reference type. Add a test for this and the rest of [dcl.mptr]p3.

common bits used for template argument deduction from a function call
and when taking the address of a function template.
