Indeed, I was not very awake when I committed that code.  I just
reverted the change so the byte-compiler simply doesn't optimize this case.
To do any better, I think we'll have to do something like:

loop over all args, doing "byte-compile-form" + "dup", and then apply
the comparisons backward, combining them with "and".
