2572 cases for old basic_string.
2573 * testsuite/21_strings/basic_string/cons/char/8.cc: Test
2574 allocator-extended constructors unconditionally. Add extra members to
2575 allocator type when using old string ABI.

2584 explicit_instantiation/debug.cc: Remove XFAIL for old ABI.

2591 (path::pop_back(), path::_M_erase_from(const_iterator)): New member
2592 functions that will only erase elements at the end.
2593 * src/filesystem/std-path.cc (path::_List::_Impl::pop_back()): Define.
2594 (path::_List::_Impl::_M_erase_from(const_iterator)): Define.
2595 (path::_List::operator=(const _List&)): Use _M_erase_from(p) instead
2597 (path::_List::pop_back()): Define.
2598 (path::_List::_M_erase_from(const_iterator)): Define.
2599 (path::operator/=(const path&)): Use pop_back to remove last component
2600 and _M_erase_from to remove multiple components.
2601 (path::_M_append(basic_string_view<value_type>)): Likewise.
2602 (path::operator+=(const path&)): Likewise.
2603 (path::_M_concat(basic_string_view<value_type>)): Likewise.
2604 (path::remove_filename()): Likewise.
2605 (path::lexically_normal()): Use _List::_Impl iterators instead of
2606 path::iterator. Use pop_back to remove components from the end. Clear
2607 trailing filename, instead of using erase(const_iterator) to remove
2608 a non-final component.
2609 * testsuite/27_io/filesystem/path/generation/normal.cc: Test
2611 * testsuite/27_io/filesystem/path/generation/normal2.cc: New test.

2618 move_assign_optim.cc: Avoid spurious failure when -fno-inline added
2620 * testsuite/21_strings/basic_string/modifiers/assign/wchar_t/
2621 move_assign_optim.cc: Likewise.
