[plt-scheme] what are the exact mzc flags to disable all optimizations?

It can't figure out which way this test goes (and this is promised, I
believe, by Matthew to remain stupid):

(if (zero? (random 1)) ...)

So you can use that to do things like this:

(define a 42)
(if (zero? (random 1)) (set! a a) (set! a 43))
(if (even? a) 'ok 'not-ok)
