* params.def (PARAM_MAX_PENDING_LIST_LENGTH): Add parameter to
limit length of dependancy flush list.
* params.h (MAX_PENDING_LIST_LENGTH): Define.
* sched-int.h (struct deps): Add pending_flush_length field.
* sched-deps.c (flush_pending_lists): Last_pending_memory_flush now
has 1 element in it.
(sched_analyze_1): Use MAX_PENDING_LIST_LENGTH.
(sched_analyze): After a jump, if the pending memory flush list is too
large, flush the pending lists.
(init_deps): Initialize pending_flush_length to 0.
* doc/invoke.texi (max_pending_list_length): Document parameter.
