  New Revision: 62641

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=62641

  Log:
    vm.c: add mjit_enable_p flag
    
    to count up total calls properly. Some places (especially CALL_METHOD)
    invoke mjit_exec twice for one method call. It would be problematic when
    debugging, or possibly it would result in a wrong profiling result.
