Set the `first` element of this bucket to the specified `node`. The behavior is undefined unless `node` is an element from the same bidirectional list as the `last` element in this bucket, and `node` either precedes `last` in that list, or is the same node, or this bucket is empty and `node` has a null pointer value.
