* config/i386/i386.md (addti3 splitter): Pass arrays of 3 operands

        to split_ti instead of three separate calls with single member arrays.
        (subti3 splitter): Ditto.
        (adddi3 splitter): Ditto with split_di.
        (subdi3 splitter): Ditto.
        (negti2 splitter): Pass arrays of 2 operands to split_ti instead of
        two separate calls with single member arrays.  Swap match_dup
        operands 1 and 2 to better fit into the array.
        (negdi2 splitter): Ditto with split_di.
        (movdfcc splitter):  Pass arrays of 2 operands to split_di instead of
        two separate calls with single member arrays.  Swap match_dup operands
        6 and 7 to better fit into the array.
