DATA_ALIGNMENT vs. DECL_USER_ALIGNMENT

    Ulrich's experience clearly belies this.

What I meant is that the Ada front end doesn't set it, not that it
isn't getting set.  Instead, it gets set from TYPE_USER_ALIGN, which
seems wrong to me because it doesn't properly distinguish (in any
language) the cases where an alignment is specified for a type
vs. when its specified for a decl.
