    Description

      With upcoming G1 remembered set changes (JDK-8017163) which extensively use the CHT it would be advantageous to have a combined insert_and_get() method to decrease the amount of global synchronization needed as after inserting a node the code always works with it.

      I.e. instead of

      bool found = cht.insert(...)
      [do something if found]
      cht.get(..., found);
      return found.value();

      it would be nice to avoid the second global synchronization by

      bool found = cht.insert_and_get(..., found, ..);
      [do something if found]
      return found.value();
