* genautomata.c (process_state_longest_path, max_dfa_issue_rate)
(output_dfa_max_issue_rate, locked_states_num): Delete.
(struct automaton): Add locked_states field.
(output_dead_lock_vect): Save number of locked states in
automaton->locked_states. If it is zero, don't print anything.
(output_max_insn_queue_index_def): Define max_insn_queue_index const.
(output_internal_dead_lock_func): Only test the dead_lock_vect
for automata that have locked states.
(output_statistics): Always print the number of locked states for
each automaton. Calculate total number of locked states here.
(write_automata): Don't call output_dfa_max_issue_rate.
* genattrtab.c: Define length_unit_log as a const variable.
* genattr.c: Don't emit MAX_DFA_ISSUE_RATE. Declare
max_insn_queue_index const.
* final.c (length_unit_log): Declare const.
* doc/tm.texi: Remove all references to MAX_DFA_ISSUE_RATE.
