There's always been a little weirdness in the simplifier with regard to negation. Apparently I used to think it could lead to losing a ConvToBool (I am not 100% sure what the case that comment refered to was now though). It definitely lets us avoid some zero-extending bools to ints though (since our binary arith guys don't support bools yet), and with this the last "dubious" genFoo is gone.
