[Bug libstdc++/42925] Not possible to compare unique_ptr with 0

I see. In principle I think the user would like to see only

  operator!=(int, int) <built-in>

and indeed:

  template<typename _Tp, typename _Tp_Deleter,
           typename _Up, typename _Up_Deleter>
    bool
    operator!=(const unique_ptr<_Tp, _Tp_Deleter>&,
               const unique_ptr<_Up, _Up_Deleter>&);

but I understand those overloads for std::error_condition / std::error_code
combinations cannot be avoided...
