Function _mm256_mask_cmp_ps_mask

#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub fn _mm256_mask_cmp_ps_mask(k1: __mmask8, a: __m256, b: __m256, IMM8: i32) -> __mmask8

Compare packed single-precision (32-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 k1 (elements are zeroed out when the corresponding mask bit is not set).
