[New-bugs-announce] [issue31384] marshal: remove "current_filename" optimization

New submission from Benjamin Peterson:

marshal current saves the the last filename it saw in a code object during deserialization, and tries to reuse it across multiple code objects to save memory. This optimization is superseded by the more general ref mechanism.
