I need an efficient way to select 2 largest integers from array of 4, preserving the order.
E.g. 1,4,3,5 -> 4,5; 1,5,3,4 -> 5,4

What’s the efficient way to do it?

I.e., with minimum conditionals (comparisons), or using min/max (assuming min/max have dedicated HW instructions and are not conditionals).
