Function _mm_maskz_cvt_roundss_sd

#[target_feature(enable = "avx512f")]
pub fn _mm_maskz_cvt_roundss_sd(k: __mmask8, a: __m128d, b: __m128, SAE: i32) -> __m128d

Convert the lower single-precision (32-bit) floating-point element in b to a double-precision (64-bit) floating-point element, 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.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
