Remove --param max-fsm-thread-length
This removes max-fsm-thread-length which is obsoleted by max-jump-thread-paths. * doc/invoke.texi (max-fsm-thread-length): Remove. * params.opt (max-fsm-thread-length): Likewise. * tree-ssa-threadbackward.cc (back_threader_profitability::profitable_path_p): Do not check max-fsm-thread-length.
