This check has been broken, because `sizeof` didn't take into the account that
`Type` objects are actually laid out in memory on 16-byte boundary, which
results in 24 bytes of data and 8 bytes of padding. My change just affirms the
status quo that Type is indeed takes 16 bytes more memory than `ExtQuals`,
which has size 16.
