TruffleRuby Native: Fast Even for Short Scripts

There seems to be essentially 2 categories in these benchmarks. Scripts which take less than 1 second and on which none of the implementations with a JIT runs faster than MRI trunk. But the JIT implementations also don’t take more than 1 second, so it’s likely not a big difference to the user. For scripts which run for more than 1 second, TruffleRuby Native saves a significant amount of time (exce
