Given this patch is of the same type as the previous one, I have also
benchmarked it, here are the results:
| instr | size |
+--------+--------+
before | 101258 | 344829 |
after | 101258 | 344833 |
This time the patch clearly doesn't bring an improvement, so I think it
should also be rewritten without the constraints change.
