Function _mm_rcp14_pd
#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub fn _mm_rcp14_pd(a: __m128d) -> __m128dCompute the approximate reciprocal of packed double-precision (64-bit) floating-point elements in a, and store the results in dst. The maximum relative error for this approximation is less than 2^-14.
