   6         __first != __last.
   7         (_Insert_base::_M_insert_range(_Ite, _Ite, _NodeGetter, true_type)): New.
   8         (_Insert_base::_M_insert_range(_Ite, _Ite, _NodeGetter, false_type)):
   9         Add false_type parameter.

  12         Adapt.
  13         (_Hashtable::_M_insert(_Arg&&, const _NodeGen&, true_type, size_t)):
  14          Add __n_elt parameter, defaulted to 1.
  15         (_Hashtable::_M_insert_unique_node): Likewise. Use it to call rehash
  16         policy _M_need_rehash.
  17         (_Hashtable::_M_merge_unique): Pass target number of elements to add to
  18         produce only 1 rehash if necessary.

  26         type for pointer stored by shared_ptr, weak_ptr and unique_ptr.
  27         (SharedPointerPrinter, UniquePointerPrinter): Treat stored values as
  28         children.
