        * include/experimental/array (make_array): Use common_type<_Dest>
        and delay instantiation of common_type until after conditional_t.
        Qualify std::forward call.
        (to_array): Add exception specification.
        * testsuite/experimental/array/make_array.cc: Test argument types
        without a common type.
