Add assertion to _Rb_tree::erase to check for end iterators
* include/bits/stl_tree.h (_Rb_tree::_M_erase_aux(const_iterator)): Add assertion for undefined argument. (_Rb_tree::_M_erase_aux(const_iterator, const_iterator)): Call _M_erase_aux directly instead of through erase. (_Rb_tree::_M_erase_aux(const Key&)): Likewise. * testsuite/23_containers/map/modifiers/erase/end_neg.cc: New test. From-SVN: r243757
