pub unsafe fn _mm_mulhrs_epi16(a: __m128i, b: __m128i) -> __m128i
This is supported on x86-64 and target feature
Multiplies packed 16-bit signed integer values, truncate the 32-bit
product to the 18 most significant bits by right-shifting, round the
truncated value by adding 1, and write bits
[16:1] to the destination.
