Multiply the lower complex number in a by the complex conjugate of the lower complex number in b, accumulate to the lower complex number in c, and store the result in the lower elements of dst using writemask k (the element is copied from a when the corresponding mask bit is not set), and copy the upper 6 packed elements from a to the upper elements of dst. Each complex number is composed of two adjacent half-precision (16-bit) floating-point elements, which defines the complex number complex = vec.fp16[0] + i * vec.fp16[1], or the complex conjugate conjugate = vec.fp16[0] - i * vec.fp16[1].
