SIMD execution policy.

When this execution policy is used in an algorithm, callables passed to the algorithm are invoked with multiple elements from the input range(s) packed into one or more simd arguments.

Examples:

vir::transform(vir::execution::simd.prefer_aligned(), input_rg, output_rg,
  [](auto v) {
    return v + v;
  });
 
vir::for_each(vir::execution::simd.unroll_by<3>(), rg, [](auto& v) { v += v; });
