	PR libstdc++/24975
	* include/bits/stl_set.h (insert(iterator, const value_type&),
	erase(iterator), erase(iterator, iterator)): Don't break aliasing
	rules casting to _Rep_iterator&, forward to _Rb_tree facilities.
	* include/bits/stl_multiset.h (insert(iterator, const value_type&),
	erase(iterator), erase(iterator, iterator)): Likewise.
	* include/bits/stl_tree.h (_Rb_tree<>::_M_insert(_Const_Base_ptr,
	_Const_Base_ptr, const value_type&), insert_unique(const_iterator,
	const value_type&), insert_equal(const_iterator, const value_type&),
	erase(const_iterator), erase(const_iterator, const_iterator)): New,
	_Rb_tree<>::const_iterator counterparts of existing facilities.
