* include/std/variant (__variant_construct): Use template parameter type instead of equivalent decltype-specifier. (_Move_ctor_base<false, Types...>::_Move_ctor_base(_Move_ctor_base&&)): Replace forward with move. (_Move_ctor_base<false, Types...>::_M_destructive_move) (_Move_ctor_base<false, Types...>::_M_destructive_copy) (_Move_ctor_base<true, Types...>::_M_destructive_move) (_Move_ctor_base<true, Types...>::_M_destructive_copy): Only set the index after construction succeeds. (_Copy_assign_base<false, Types...>::operator=): Remove redundant if-constexpr checks that are always true. Use __remove_cvref_t instead of remove_reference so that is_nothrow_move_constructible check doesn't use a const rvalue parameter. In the potentially-throwing case construct a temporary and move assign it, as per LWG 2904. (_Move_assign_base<false, Types...>::operator=): Remove redundant if-constexpr checks that are always true. Use emplace as per LWG 2904. (variant::operator=(T&&)): Only use emplace conditionally, otherwise construct a temporary and move assign from it, as per LWG 2904. * testsuite/20_util/variant/exception_safety.cc: Check that assignment operators have strong exception safety guarantee.
