Sergey Glukhov af3fdefca5 Bug #14409015 MEMORY LEAK WHEN REFERENCING OUTER FIELD IN HAVING ...

When resolving outer fields, Item_field::fix_outer_fields()
creates new Item_refs for each execution of a prepared statement, so
these must be allocated in the runtime memroot. The memroot switching
before resolving JOIN::having causes these to be allocated in the
statement root, leaking memory for each PS execution.
