        * tree-vectorizer.h (vect_analyze_data_ref_dependences): Remove
        the last argument.
        * tree-vect-loop.c (vect_analyze_loop_2): Update call to
        vect_analyze_data_ref_dependences.
        * tree-vect-data-refs.c (vect_analyze_data_ref_dependence):
        Remove the last argument.  Check load-after-store dependence
        for unknown dependencies in basic blocks.
        (vect_analyze_data_ref_dependences): Update call to
        vect_analyze_data_ref_dependences.
        * tree-vect-patterns.c (vect_recog_widen_shift_pattern): Fix
        typo.
        * tree-vect-slp.c (vect_bb_vectorizable_with_dependencies):
        Remove.
        (vect_slp_analyze_bb_1): Update call to
        vect_analyze_data_ref_dependences.  Don't call
        vect_bb_vectorizable_with_dependencies.
