RTL checking is needed to reproduce this:

#ifdef ENABLE_RTL_CHECKING
...
          old_vl = simplify_replace_fn_rtx (old_vl, NULL_RTX,
                        strip_pointer_flags, NULL);
          new_vl = simplify_replace_fn_rtx (new_vl, NULL_RTX,
                        strip_pointer_flags, NULL);
          gcc_assert (rtx_equal_p (old_vl, new_vl));
...
#endif
