[lworld] RFR: 8266712: [lworld] compiler/loopstripmining/DeadNodesInOuterLoopAtLoopCloning.java fails after merge

[Tobias Hartmann]

[JDK-8189802](https://bugs.openjdk.java.net/browse/JDK-8189802) weakened the conditions for calling `can_see_stored_value` from `StoreNode::Identity` (see http://hg.openjdk.java.net/valhalla/valhalla/rev/b826402f953a#l16.35). New code added by [JDK-8263972](https://bugs.openjdk.java.net/browse/JDK-8263972) needs to be adjusted accordingly.

Best regards,
Tobias
