Function _mm_mask_fpclass_pd_mask 

pub fn _mm_mask_fpclass_pd_mask(
    k1: __mmask8,
    a: __m128d,
    const IMM8: i32,
) -> __mmask8

Available on x86-64 and target feature avx512dq and target feature avx512vl only.

Test packed double-precision (64-bit) floating-point elements in a for special categories 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). 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
