Handle insidious corner case exposed by RegionStoreManager when handling void* values that are bound
to symbolic regions and then treated like integers.

Fix up support for OptionalDefOperand when it defaults to an actual register def. I need this to get ready for major Thumb1 surgery.

MemRegion kinds. This allows the compiler to identify what MemRegions we don't
handle for pointer arithmetic.

Implement more of C++0x 'auto'. A variable with an auto type specifier must have an initializer. Also, move some tests around to match the C++0x draft better.

  warning: ‘OPT’ may be used uninitialized in this function

Now OPT is initialized to NULL. I'm not certain if this is the correct fix;
others please review.

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.

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.

Make changes suggested by Chris and eliminate newly-added raw_ostream
hooks as they're no longer needed.

The major change with this patch is to make formatted_raw_ostream usable
by any client of raw_ostream.
