Fix PR6648 by not creating a temporary with the type of a

CXXExprWithTemporaries.

Not emitting the expression as an aggregate might be the right thing to do,
but is orthogonal. Emitting it as an scalar expression will still try to
create a temporary for the incomplete type of the CXXExprWithTemporaries and
fail.
