Emil Lenngren 76e3dee4d0 [GB.JIT]
* NEW: Can now profile each line of code, but beware: profiling makes the program much much slower.

[GB.DEBUG]
* OPT: Now DEBUG_calc_line_from_position has logaritmic time complexity instead of linear. That makes profiling each line much faster for large functions!
