 * @bug 8372302
 * @summary ModINode::Ideal and ModLNode::Ideal use an intermediate "hook" node
 *          to keep stuff alive between phase->transform(...) calls. In some cases,
 *          this node is not properly deleted before returning, causing failure
 *          in the verification because the node count has changed. This test
 *          ensures that the intermediate node gets destroyed before returning.
