I hope not if this would change the layout of a structure containing a
member with the specified alignment requirement.  This is where
propagating the user-requested alignment for a type into the field
decl comes into play: by doing this, we make sure the alignment
request is obeyed, regardless of whether it comes from the field decl
or from its type.
