Update rust benchmark and test results.

I'll just be using the rust's noise.rs from now on. They maintain it, I'm
happy. And few comments from me just for fun:

- Good job GCC, it's back to being a leader.
- GCCGo, ouch. :(
- Nimrod became faster, because it targets C and compiled via gcc I think. So,
  thanks to gcc, again.
- Mono JIT became slower, who cares anyway. Unity devs should care, I guess.
