Should we also disallow the objects that return true for
`hasNonTrivialObjCLifetime`?
That's the part of the `is_trivially_copyable` that seems relevant. I don't
have a good understanding of ObjC, so I'd rather lean on the safe side here.
(I.e. maybe there are low-level ways to update the reference counters after
`memcpy`, I don't really know. But assuming there aren't, I'd rather lean on
the side of returning false for this trait)
