Purpose:

    ZLA_WWADDW adds a vector W into a doubled-single vector (X, Y).

    This works for all extant IBM's hex and binary floating point
    arithmetic, but not for decimal.

Parameters

[in]	N	N is INTEGER The length of vectors X, Y, and W.
[in,out]	X	X is COMPLEX*16 array, dimension (N) The first part of the doubled-single accumulation vector.
[in,out]	Y	Y is COMPLEX*16 array, dimension (N) The second part of the doubled-single accumulation vector.
[in]	W	W is COMPLEX*16 array, dimension (N) The vector to be added.
