Function `_mm_max_round_sh`

#[target_feature(enable = "avx512fp16", enable = "avx512vl")]
pub fn _mm_max_round_sh(a: __m128h, b: __m128h, SAE: i32) -> __m128h

Compare the lower half-precision (16-bit) floating-point elements in a and b, store the maximum value in the lower element of dst, and copy the upper 7 packed elements from a to the upper elements of dst. Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter. Does not follow the IEEE Standard for Floating-Point Arithmetic (IEEE 754) maximum value when inputs are NaN or signed-zero values.
