FDOT (half-precision to single-precision, vector)

Half-precision dot product to single-precision (vector)

This instruction calculates the fused sum-of-products of a pair of half-precision values held in each 32-bit element of the first and second source vectors, without intermediate rounding, and then destructively adds the single-precision sum-of-products to the corresponding single-precision element of the destination vector.
