    Description

      Dump latest IGV Ideal graph to a "idealgraph_pidX.xml" file when C2 crashes, similarly to how it is done with e.g. compiler replay data. If Ideal graph printing is enabled when the crash occurs (e.g. by -XX:PrintIdealGraphLevel=N), append the latest Ideal graph to the sequence of dumped graphs.

      Thanks to [~thartmann] for the original suggestion.
