Martin HS 25bc07749c core/vm: speed up push and interpreter loop (#30662 ) Looking at the cpu profile of a burntpix benchmark, I noticed that a lot of time was spent in gas-used, in the interpreter loop. It's an actual call (not inlined), which explicitly wants to be ignored by tracing ("tracing.GasChangeIgnored"), so it can be safely and simply inlined. The other change is in `pushX`. These also do a call to `common.RightPadBytes`. I replaced that by a doing a corresponding `Lsh` on the `u256` if needed. Note: it's needed only to make the stack output look right, for fuzzers. It technically doesn't matter what we put there: if code ends on a pushdata immediate, nothing will consume the stack element. We could just as well just ignore it, if we didn't care about fuzzers (which I do). Seems quite a lot faster on burntpix, according to my runs.
