#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub fn _mm_maskz_roundscale_pd(k: __mmask8, a: __m128d, IMM8: i32) -> __m128dRound packed double-precision (64-bit) floating-point elements in a to the number of fraction bits specified by imm8, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
Rounding is done according to the imm8[2:0] parameter, which can be one of:\
