[qfcc] Set all the commutativity flags

Browse source 
Including anti-commutativity. I hadn't set them before because I was
uncertain and got conflicting answers, but when I took a look again, it
seems IEEE 754 does guarantee commutativity for multiplication and
addition, so long as NaN isn't involved (and then it seems to be because
`a==a` is always false when a is a NaN).
