    Fix PR ada/98228

    This is the profiled bootstrap failure for s390x/Linux on the mainline,
    which has been introduced by the modref pass but actually exposing an
    existing issue in the maybe_pad_type function that is visible on s390x.

    The issue is too weak a test for the addressability of the inner component.

            * gcc-interface/utils.c (maybe_pad_type): Test the size of the new
            packable type instead of its alignment for addressability's sake.
