Chunk generator performance survey

[Seadragon91]

I compiled a binary with gcc 6 and clang 3.9.1. This are the result from 3 runs for every binary. Used only world no nether and no the end.

In world/world.ini changed:
PregenerateDistance to 100
Seed to 42

As you can see gcc beats clang. I didn't changed anything in the source and added no flags.
