        Having introduced the RepatchBuffer, ProcessorReturnAddress is now a do-nothing
        wrapper around ReturnAddressPtr.  Remove it.  In tugging on this piece of string
        it made sense to roll out the use of ReturnAddressPtr a little further into
        JITStubs (which had always been the intention).

        No performance impact.
