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.
