 （C++11 起）
提供的的成员typedeftype，这是一个POD类型适合用作未初始化的存储，一个目的的任何类型中列出Types正确对齐。所述存储的大小是至少Len。 std::aligned_union也决定了严格的（最大）之间的对齐要求所有Types，使得它可以作为不断alignment_value.
Original:
Provides the member typedef type, which is a POD type suitable for use as uninitialized storage, correctly aligned for an object of any of the types listed in Types. The size of the storage is at least Len. std::aligned_union also determines the strictest (largest) alignment requirement among all Types and makes it available as the constant alignment_value.
