        * combine.c (gen_binary): Remove.
        (known_cond, simplify_shift_const
        find_split_point, combine_simplify_rtx,
        simplify_if_then_else, simplify_set,
        simplify_logical, expand_field_assignment,

        simplify_and_const_int, simplify_shift_const,
        gen_lowpart_for_combine, simplify_comparison,
        reversed_comparison): Replace with
        simplify_gen_binary, simplify_gen_relational or
        distribute_and_simplify_rtx.
        (distribute_and_simplify_rtx): New function.
        * simplify-rtx.c (simplify_binary_operation):
        Use nonzero_bits to simplify ANDs where we are
        turning off bits already known to be off in OP0.
