libstdc++: Add comparison operators to types from Numerics clause
Some more C++20 changes from P1614R2, "The Mothership has Landed".
* include/bits/slice_array.h (operator==(const slice&, const slice&)):
Define for C++20.
* include/std/complex (operator==(const T&, const complex<T>&))
(operator!=(const complex<T>&, const complex<T>&))
(operator!=(const complex<T>&, const T&))
(operator!=(const T&, const complex<T>&)): Do not declare for C++20.
* testsuite/26_numerics/slice/compare.cc: New test.
