Michael Widenius fb018850dc Fixed that setup_natural_join_row_types can safely be called twice ...

sql/item.h:
  Added cache for setup_natural_join_row_types
sql/sql_base.cc:
  Cache old value of first_name_resolution_table for next call.
  (It's not safe to try to recalculate the value as the join structure may have been changed by the optimizer)
