Function `_mm256_mask_rorv_epi64`

#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub const fn _mm256_mask_rorv_epi64(src: __m256i, k: __mmask8, a: __m256i, b: __m256i) -> __m256i

Rotate the bits in each packed 64-bit integer in a to the right by the number of bits specified in the corresponding element of b, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
