Function _mm_cvt_roundsh_sd

#[target_feature(enable = "avx512fp16")]
pub fn _mm_cvt_roundsh_sd(a: __m128d, b: __m128h, SAE: i32) -> __m128d

Convert the lower half-precision (16-bit) floating-point element in b to a double-precision (64-bit) floating-point element, store the result in the lower element of dst, 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.
