Function `_mm256_mask_cmp_ph_mask`

#[target_feature(enable = "avx512fp16", enable = "avx512vl")]
pub fn _mm256_mask_cmp_ph_mask(k1: __mmask16, a: __m256h, b: __m256h, IMM5: i32) -> __mmask16

Compare packed half-precision (16-bit) floating-point elements in a and b based on the comparison operand specified by imm8, and store the results in mask vector k using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
