But I don't know how to query the alignment of an object rather than a type.

Shouldn't ( & object [ 0 ] ) % 16 == 0 do the trick?

There's quite a large difference between "this object happens to land on a 16 byte alignment" and "what is the alignment of this object?" or even "is this object alignas(16)".
