Paul Keir eb11134d0c 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.
