pub unsafe fn _mm_hadds_epi16(a: __m128i, b: __m128i) -> __m128i
This is supported on x86-64 and target feature
Horizontally adds the adjacent pairs of values contained in 2 packed
128-bit vectors of
[8 x i16]. Positive sums greater than 7FFFh are
saturated to 7FFFh. Negative sums less than 8000h are saturated to 8000h.
