libstdc++: Missing constexpr for __gnu_debug::__valid_range etc
The new 25_algorithms/move/constexpr.cc test fails in debug mode,
because the debug assertions use the non-constexpr overloads in
<debug/stl_iterator.h>.
libstdc++-v3/ChangeLog:
* include/debug/stl_iterator.h (__valid_range): Add constexpr
for C++20. Qualify call to avoid ADL.
(__get_distance, __can_advance, __unsafe, __base): Likewise.
* testsuite/25_algorithms/move/constexpr.cc: Also check with
std::reverse_iterator arguments.
