can it not be beneficial to make the fold if either LHS or RHS have one use? it will result in the same amount of instructions but the other argument will have one less use.

The cmp that has one use would also need its op to have one use i.e
(LHS->hasOneUse() && LHS0->hasOneUse()) || (RHS->hasOneUse() && RHS0->hasOneUse())
. And that would only make it break even.
