This makes the analysis for code/data faster, and more evenly spread. Previously, the worst-performing case was PUSH7.
PUSH1 started at ~40ns, and going upwards towards 50ms at PUSH7.
This PR doesn't improve the PUSH1 situation, but does markedly improve the (previous) worst-case quite a lot, and also the normal-case (for code which is not push).
