        * bb-reorder.c (find_traces_1_round): decreate_key is replaced
    with replace_key method.
    * fibonacci_heap.h (fibonacci_heap::insert): New argument.
    (fibonacci_heap::replace_key_data): Likewise.
    (fibonacci_heap::replace_key): New method that can even increment key,
    this operation costs O(log N).
    (fibonacci_heap::extract_min): New argument.
    (fibonacci_heap::delete_node): Likewise.
