Shouldn't COMPLETE_TYPE_P imply that we can compute the size of the
type?  That's the requisite we need in this case to emit the load from
the volatile reference.  Otherwise, we have no other choice but to throw
it away.

ISTM that if COMPLETE_TYPE_P had the right sizeof semantics, we wouldn't
need the workaround added for 23167.
The only thing the gimplifier can do in this case is throw the reference
out, but
