You could always do what I did in my D SHA implementations:
uint something = whatever;
asm { rol something, 5; }
something += stuff;
We have inline asm, so I say just go ahead and use it.
The problem with asm is portability. You can't go very far from x86
with the above code, and if you do you end up with static ifs
everywhere, adding a readability problem.
So an intrinsic or a built-in operator is much better.
