Function _mm256_mask_fpclass_ph_mask

#[target_feature(enable = "avx512fp16", enable = "avx512vl")]
pub fn _mm256_mask_fpclass_ph_mask(k1: __mmask16, a: __m256h, IMM8: i32) -> __mmask16

Test packed half-precision (16-bit) floating-point elements in a for special categories 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). imm can be a combination of:

0x01 // QNaN
0x02 // Positive Zero
0x04 // Negative Zero
0x08 // Positive Infinity
0x10 // Negative Infinity
0x20 // Denormal
0x40 // Negative
0x80 // SNaN
