Ok, I thought my change was better because we have many allocator types
in tests without operator ==/!= (see
23_containers/*/cons/noexcept_default_construct.cc). But of course the
tests are not making any use of it for the moment, no big deal.
So this patch is just an optimization, may I still commit it ? Unless
you like the fact that Debug mode is checking that those operators are
provided when allocator-aware move constructor is being used.
