   On 64 bit Windows, stack alignment on a 16 byte boundary is required   
   before calling all except a leaf function. In the called function, the   
   stack is 8 mod 16.   
      
   Now, I'm struggling to come up with a way of doing it beyond this code   
   (which I didn't invent, but I can't for the life of me remember where I   
   found it.)   
      
      push   rsp   
      push   [rsp]   
      and    spl $F0   
      call   funkychicken   
      pop    rsp   
      
   It seems to be the only way of doing this without branches, flags or   
   other expensive nonsense. But, as ever, there may be a better way. Any   
   suggestions?
