reorganize: Adjust padding after moving from the tail 

When we move fields from the tail to eliminate holes look if the struct
still correctly fits into a multiple of cu->addr_size.

Unless the struct is explicitely marked __attribute__((packed)) (and we
can't know that for sure) we have to add padding in that case.
