even with no code gen difference i find

 r = f(c?x:y, u, v, w);

cleaner than

 if (c)
   r = f(x, u, v, w);
 else
   r = f(y, u, v, w);

because the first one makes it clear that only one arg is
changed based on c, the rest of the logic is the same

(maybe the c?x:y should be done on a separate line if the
call becomes too long)
