Function _mm_maskz_sub_round_sd

#[target_feature(enable = "avx512f")]
pub fn _mm_maskz_sub_round_sd(k: __mmask8, a: __m128d, b: __m128d, ROUNDING: i32) -> __m128d

Subtract the lower double-precision (64-bit) floating-point element in b from the lower double-precision (64-bit) floating-point element in a, store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper element from a to the upper element of dst.\

Rounding is done according to the rounding[3:0] parameter, which can be one of:\
