RFR: 8361238: G1 tries to get CPU info from terminated threads at shutdown

Hi all,

  please review this fix after the recent changes in void JDK-8274051 where G1 tries to get thread cpu time on already terminated threads.

The fix is to move the printing/statistics before stopping the threads. This seems fine for the two implementors of the method.

In a future change, since so few GCs implement `print_tracing_info`, the call should probably move to `stop()/begin_exit()`.

Testing: gha

Thanks,
  Thomas
