nemobench5 evolution

bench5 was calibrated to be 1000.0 on kubuntu20 (?)

On Kubuntu23.04 (beta!!) gcc 12.2.0 is clearly regressing to ~900

 CPU_USAGE  treecode1   :  4.94  4.94  0.00  0.00  0.00  1718012540

mostly due to potcode and orbint, in this case.

this could also be a more conservative setting of the cpu freqs..... laptops are just terrible to use for benchmarking. As a new kubuntu was installed, one never knows how they tuned the cpu freqs... just a thought.
