        * tree-vect-analyze.c (vect_analyze_operations): RELEVANT and LIVE
stmts
        need to be checked for success seperately.
        * tree-vect-transform.c (vectorizable_call, vectorizable_conversion):
        Remove the check that stmt is not LIVE.
        (vectorizable_assignment, vectorizable_induction): Likewise.
        (vectorizable_operation, vectorizable_type_demotion): Likewise.
        (vectorizable_type_promotion, vectorizable_load, vectorizable_store):
        Likewise.
        (vectorizable_live_operation): Check that op is not NULL.
