    Original commit message:
        Int64Add is lowered to a new turbofan operator, Int32AddPair. The new
        operator takes 4 inputs an generates 2 outputs. The inputs are the low
        word of the left input, high word of the left input, the low word of the
        right input, and high word of the right input. The ouputs are the low
        and high word of the result of the addition.
