Brainfuck compilersuite

After implementing a "Brainfuck to COBOL"-compiler I became inspired to implement other compilers as well.

Below you will find the whole collection of brainfuck compilers and how well the resulting code performs.
For each I tested the run-time of the brainfuck mandelbrot implementation. Where possible I used the "-flto -O3 -march=native -fomit-frame-pointer" compiler flags.
The compilers to do these compilations/conversions are in GitHub.
