    * cselib.c (new_elt_loc_list): When moving locs from one
    cselib_val to its new canonical_cselib_val and the
    cselib_val was in first_containing_mem chain, but
    the canonical_cselib_val was not, add the latter into the
    chain.
    (cselib_invalidate_mem): Compare canonical_cselib_val of
    addr_list chain elt with v.
