The problem is that, as far as I know, a conditional move is going to introduce a data dependency from c0 to c1 to c2 that is the exact thing we are trying to get rid of. The cmov is a constant time instruction, not a speculated instruction like a conditional branch.
The entire point of what I did is that the two conditional branches will be predicted not taken, so the CPU will 99.9999999999999999946% of the time not even see the `c1 = c0` and `c2 = c1` instructions that introduce the sequential dependencies.
