[PATCH] MCJIT MachO debugging support

[Keno Fischer]

Hi Lang,

thanks for taking a look. When I originally wrote this code, I had an idea on how to do it, but I don't think it actually works the way I had hoped, especially because MachO makes the assumption on the original object file lay out in other places as well. I think I'm just to push a new version that removes that comment.
