This reorders the data members of _Utf_iterator to avoid padding bytes
between members due to alignment requirements. For x86_64 the previous
layout had padding after _M_buf and after _M_to_increment for the common
case where the iterators and sentinel types are pointers, so the size
shrinks from 4
