Inserts stuff before, after, or instead range r, which must
be a valid range previously extracted from this container. stuff
can be a value convertible to the container's element type or a range
of objects convertible to it. The stable version behaves the same, but
guarantees that ranges iterating over the container are never
invalidated.
