libstdc++: Remove workaround in __gnu_cxx::char_traits::move [PR89074]
The front-end bug that prevented this constexpr loop from working has
been fixed since GCC 12.1 so we can remove the workaround.
libstdc++-v3/ChangeLog:
PR c++/89074
* include/bits/char_traits.h (__gnu_cxx::char_traits::move):
Remove workaround for front-end bug.
