Do not attempt to produce "r_engine_stats" on the temporary (=work) tables. These tables may be - re-created during the query execution - freed during the query execution (This is done e.g. in JOIN::cleanup(), before we produce ANALYZE FORMAT=JSON output). - (Also, make save_explain_data() functions not set handler_for_stats to point to handler objects that do not have handler->handler_stats set. If the storage engine is not collecting handler_stats, it will not have them when we're producing ANALYZE FORMAT=JSON output, either).
