        * tree-vectorizer.h (vect_make_slp_decision): Return bool.
        * tree-vect-loop.c (vect_analyze_loop_operations): Add new
        argument to indicate if loop aware SLP is being used.  Scan
        the statements and update the vectorization factor
        according to the type of
        vectorization before statement analysis.
        (vect_analyze_loop_2): Get a return value from
        vect_make_slp_decision, pass it to 
        vect_analyze_loop_operations.
        (vectorizable_reduction): Set number of copies to 1 in case of
        pure SLP statement.
        * tree-vect-stmts.c (vectorizable_conversion,
        vectorizable_assignment, vectorizable_shift,
        vectorizable_operation, vectorizable_type_demotion,
        vectorizable_type_promotion, vectorizable_store,
        vectorizable_load): Likewise.
        (vectorizable_condition): Move the check that it is not SLP
        vectorization before the number of copies check.
        * tree-vect-slp.c (vect_make_slp_decision): Return TRUE if
        decided to vectorize the loop using SLP.
