1BRC in Scala and Scala Native

[lbialy]

Hey, I've decided to use 1BRC to test how close Scala Native (a bridge to compile otherwise JVM-bound Scala applications to native binaries via LLVM) is to having proper multithreading support. It turns out that with some optimizations it's quite close. This isn't really a submission to make it BRRRRR as fast as possible, it's rather a comparison of two runtimes for Scala. More information about what we did is available here at my fork:

Thank you @gunnarmorling for this opportunity!
