Purpose:
    DLA_WWADDW adds a vector W into a doubled-single vector (X, Y).

    This works for all extant IBM's hex and binary floating point
    arithmetics, but not for decimal.
Parameters
[in]N
          N is INTEGER
            The length of vectors X, Y, and W.
[in,out]X
          X is DOUBLE PRECISION array, dimension (N)
            The first part of the doubled-single accumulation vector.
[in,out]Y
          Y is DOUBLE PRECISION array, dimension (N)
            The second part of the doubled-single accumulation vector.
[in]W
          W is DOUBLE PRECISION array, dimension (N)
            The vector to be added.
