#[target_feature(enable = "avx512f")]
pub unsafe fn _mm512_i64gather_ps(offsets: __m512i, slice: *const f32, SCALE: i32) -> __m256Gather single-precision (32-bit) floating-point elements from memory using 64-bit indices. 32-bit elements are loaded from addresses starting at base_addr and offset by each 64-bit element in vindex (each index is scaled by the factor in scale). Gathered elements are merged into dst. scale should be 1, 2, 4 or 8.
