> Here is an implementation of loop unrolling optimization.
> The patch enables it in all modes with Jitrino.OPT we have.
> There are some TODOs, described in loop_unroll.cpp files, read it if you are interested to write minitests to see performance improvements.
> My minitests shows that we have ~50% improvement on classic BubbleSort application and ~15% for Arrays.sort when dynamic edge profile is used.
