libstdc++: Fix char_traits move with overlap
Upon constexpr evaluation, char_traits move uses copy_backward, but its
last argument should be to the range end rather than its beginning.
2020-06-12 Paul Keir <paul.keir@uws.ac.uk>
* include/bits/char_traits.h (char_traits::move): constexpr move with
overlap was using copy_backward incorrectly.
* testsuite/21_strings/char_traits/requirements/constexpr_functions_c++20.cc:
New test.
