* sel-sched-ir (sel_init_new_insn): New parameter old_seqno.
Default it to -1. Pass it down to init_simplejump_data.
(init_simplejump_data): New parameter old_seqno. Pass it down
to get_seqno_for_a_jump.
(get_seqno_for_a_jump): New parameter old_seqno. Use it for
initializing new jump seqno as a last resort. Add comment.
(sel_redirect_edge_and_branch): Save old seqno of the conditional
jump and pass it down to sel_init_new_insn.
(sel_redirect_edge_and_branch_force): Likewise.
