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)
