Synopsis
 _mm_fmadd_sd(__m128d a, __m128d b, __m128d c);
Description
Multiply the lower double-precision (64-bit) floating-point elements in "a" and "b", and add the intermediate result to the lower element in "c". Store the result in the lower element of "dst", and copy the upper element from "a" to the upper element of "dst".
Operation
dst[63:0] := (a[63:0] * b[63:0]) + c[63:0]
dst[127:64] := a[127:64]
dst[MAX:128] := 0
