Add more test cases

When #5 were merged, we should add more test cases.

What can be edge case for this?

@odeke-em I think we can remove the TODO about the "_ [0]func()", because if it's already the first field of struct, it will always be there.

_ [0]func has size 0 and align of 8, so it always goes before others when we sort fields.
