      Returns the distance betweenbasic_const_iterator and its sentinel.

      S satisfies the exposition-only concept/*not-a-const-iterator*/ if and only if it's not a specialization ofbasic_const_iterator.

      i, s - iterator and sentinel to compute the difference of

      [edit]Return value

      1)base()- s
      2)s- i.base()
