Multiplies the 8 signed or unsigned 16-bit integers from a by the 8 signed or unsigned 16-bit integers from b.
__m128i _mm_mullo_epi16 (__m128i a, __m128i b); PMULLW
Packs the lower 16 bits of the 8 signed or unsigned 32-bit results.
r0 := (a0 * b0)[15:0] r1 := (a1 * b1)[15:0] ... r7 := (a7 * b7)[15:0]
