Notes:
This pointer is only valid until notify_tables_are_closed() is called.
After that, the tables may be freed or reused, together with their

notify_tables_are_closed() disables printing of FORMAT=JSON output.
r_engine_stats is only printed in FORMAT=JSON output, so we're fine.
We do not store pointers to temporary (aka "work") tables here.
Temporary tables may be freed (e.g. by JOIN::cleanup()) or re-created
during query execution (when HEAP table is converted into Aria).
