While I think that this should be fixed, it will only prevent that I would
directly convert is_constructible to use the combined
::delete ::new ((void*) nullptr) T(args)
expression. Our current implementation is not sensitive to this problem,
because we use is_destructible within. I noticed that there are still a bunches
of opportunities to simplify is_constructible (and friends) because a lot of
previous compiler defects have been fixed. So, really no need to hurry!
