Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for a
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.
