      Description

        Not all ideal nodes are added to the connection graph, it will result in a crash, though, if a node
        n that was not added to the connection graph is passed to ConnectionGraph::not_global_escape(Node* n).
        This case should be handled more gracefully by returning false.

        This is split off from JDK-8227745. There not_global_escape() is applied to the arguments of java
        calls. If e.g. one should be an integer constant not_global_escape() would crash.
