Change core to use repr->twoPtrValue.ptr1 in stead of repr->otherValuePtr (which is exactly the same), but also set repr->twoPtrValue.ptr2 to NULL explicitly.
This allows repr->twoPtrValue.ptr2 to be used for another purpose (experimental): Store the StringObj internal representation there when available.
