        * tree-vectorizer.h (vect_is_simple_use): Add an argument.
        (vect_is_simple_use_1): Likewise.
        * tree-vect-loop.c (vectorizable_reduction): Update calls
        to vect_is_simple_use_1 and vect_is_simple_use.
        (vectorizable_live_operation): Likewise.
        * tree-vect-patterns.c (widened_name_p,
        vect_recog_vector_vector_shift_pattern, check_bool_pattern):
        Likewise.
        * tree-vect-stmts.c (process_use, vect_get_vec_def_for_operand,
        vectorizable_call, vectorizable_conversion,
        vectorizable_assignment, vectorizable_shift,
        vectorizable_operation, vectorizable_store, vectorizable_load):
        Likewise.
        (vect_is_simple_cond): Add an argument, pass it to
        vect_is_simple_use_1.
        (vectorizable_condition): Update calls to vect_is_simple_cond,
        vect_is_simple_use.
        (vect_is_simple_use): Add an argument, the statement in which
        OPERAND is used.  Check that if OPERAND's def stmt is a double
        reduction phi node, the use is a phi node too.
        (vect_is_simple_use_1): Add an argument, pass it to
        vect_is_simple_use.
        * tree-vect-slp.c (vect_get_and_check_slp_defs): Update a call
        to vect_is_simple_use.
