For the raw pointer constructor, check that the argument is not on the stack. Passing a stack pointer as an sp<> parameter is dangerous, since we will attempt to deallocate the object once the sp<> is no longer needed. We approximate ste stack ccheck by testing whether it is on the same page as the frame pointer. Do the same for raw pointer assignment.
