Brainfuck JIT compiler

I wanted to learn more about how JITs work, so I wrote one! So far this doesn't do anything terribly exciting besides being much, much faster than your average brainfuck interpreter, but it does currently do a few neato optimizations:

• Convert runs of operations like + or > into single ops
• Turns [-] into a single "set current cell to 0" op

Building it

This was written and tested on a 64 bit i386 Linux machine, and as far as I can tell that's the only place it'll run.

$ gcc -m64 main.c -o bfjit
$ ./bfjit tests/mandelbrot.b
