--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Indeed:

(gdb) p debug_generic_expr (t1)
OBJ_TYPE_REF(_7;&objc_super->0)
$1 = void
(gdb) p debug_generic_expr (t2)
OBJ_TYPE_REF(_7;&objc_super->0)
$2 = void

I think dispatching to compare_ssa_name is premature optimization - just use
compare_operand?
