Moved tracking the current PID to the modules

The privatized object count was previously tracked via in the runtime.
Now, it is an atomic integer in the modules that is passed into the
runtime when creating new privatized classes.
Updated some .goods that changed after moving the pid into the modules
Convert PIDs to be int(64) and count with a processor atomic
Fixing glob iterator test so that it no longer fails on multilocale testing (bad .good file)
Update .bad file to reflect that we now generate an error instead of a warning
when we trigger "control flow reached end of function that returns a value".
