比較底層迭代器/哨兵。

令 current_ 為底層迭代器，end_ 為底層哨兵。

1) 等價於 return x.current_ == x.end_;。

2) 等價於 return x.current_ == y.current_;。

3) 等價於 return x.current_ < y.current_;。

4) 等價於 return y < x;

5) 等價於 return !(y < x);

6) 等價於 return !(x < y);

7) 等價於 return x.current_ <=> y.current_;。

這些函式對普通的非限定查詢或限定查詢不可見，只有當std::ranges::stride_view::iterator<Const>是引數的關聯類時，才能透過實參依賴查詢找到它們。

!= 運算子由 operator== 合成。
