This simplifies the implementation, and is more secure, because you no
longer can compare const_iterator with const_iterator and get a
non-sensical result (unequal, even though copies of each other).
Requires the STL algorithm test to be ported to C++20 ranges, because
classical STL algorithms can't deal with decltype(first) !=
decltype(last).
Found in API-review.
As a drive-by, make the reversed and inverted operators conditional on
!__cpp_impl_three_way_comparison.
