    PR middle-end/56461
    * tree-ssa-loop-niter.c (bb_queue): Remove typedef.
    (discover_iteration_bound_by_body_walk): Change queues to
    vec<vec<basic_block> > and queue to vec<basic_block>.  Fix up
    spelling in comment.  Call safe_push on queues[bound_index] directly.
    Release queues[queue_index] in every iteration unconditionally.
    Release bounds vector.
