[qfcc] Commit common scale terms

While it works, and does improve the code slightly, it could do better
by favoring constants over variables for the common factor.

That is, `x+x -> 2*x` (and similar for higher counts). Doesn't make much
difference for just 2, but it will make collecting scales easier and I
remember some testing showing that `2*x` is faster than `x+x` for
floating point.

Of course, motor-point keeps bouncing around numerically :/
