A pragma would help all that much, because the condition is determined too
early (preprocessing time). To construct a stack-based variant class we need
to be able to determine the alignment when we instantiate.

I personally don't see much of a reason to add this capability into the core
language. It is clearly possible from the library standpoint once we have an
accurate alignof().
