backport: re PR rtl-optimization/40101 (200.sixtrack ICEs in get_seqno_by_preds, at sel-sched-ir.c:3752)

Backport from mainline:
        PR rtl-optimization/40101
         * sel-sched-ir.c (get_seqno_by_preds): Allow returning negative
         seqno.  Adjust comment.
         * sel-sched.c (find_seqno_for_bookkeeping): Assert that when
         inserting bookkeeping before a jump, the jump is not scheduled.
         When no positive seqno found, provide a value.  Add comment.
