Reintroduce r67870 (rval ref overloading), since I can't reproduce any test failures on i386 or x86_64. If this fails for someone, please contact me.

I was curious about how the ARM ABI works.  It should be a decent start, 
though.

More improvements to namespace aliases. We now support everything except aliases in using directives.

Let getIdentifierNamespaceForKind know about aliases and have it treat them just like namespace decls.

pointer.  Its purpose in life is to be a glorified void*, but which does not
implicitly convert to void* or other OpaquePtr's with a different UID.

Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>.  Change the 
entire parser/sema interface to use DeclPtrTy instead of DeclTy*.  This
makes the C++ compiler enforce that these aren't convertible to other opaque
types.

We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc,
but I don't plan to do that in the short term.

The one outstanding known problem with this patch is that we lose the 
bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to
bitmangle the success bit into the low bit of DeclPtrTy.  I will rectify
this with a subsequent patch.
