      Description

      During the code review of:

          JDK-8227338 templateInterpreter.cpp: copy_table() needs to be safer
          https://bugs.openjdk.java.net/browse/JDK-8227338

      The possibility of making TemplateInterpreter::_active_table volatile
      in order to limit C++ compiler optimizations was raised. This type
      of change will ripple into the various functions that manage the
      _active_table.

      Coleen also wonders what needs to happen to the _active_table
      logic when we eventually only have handshakes for safepoints.
