That's one part, but it also means that a new-style FOO-p might need to
accept old-style vector-structs rather than only records.

I tried to fix these issues by relying more on `type-of' which I tried
to make work the same way for old and new structs.

I think I also fixed the remaining test failures, tho I haven't re-run
the whole testsuite, so maybe I introduced further failures again.
