Suggested at Bug 103372.

ContainerNode::replaceChild() calls multiple checkReplaceChild() for preventing manifold tree.
But we can skip the one other than the first if we know there is no event listener fired since the last checkReplaceChild() call.
That omission will improve replaceChild() performance.
