sql/sql_select.cc:
  Changes to hook the new QUICK_GROUP_MIN_MAX_SELECT due to two differences from all other
  quick selects:
  1)
  This quick select may be created (and used) even if there is no WHERE clause.
  Several places assumed that a QUICK_SELECT is constructed only if there is a WHERE clause,
  which had to be changed so that QUICK_GROUP_MIN_MAX can be used.
  2)
  Unlike all other quick selects, this QUICK_GROUP_MIN_MAX_SELECT operates for GROUP BY queries.
  Since for the caller the quick select already produces one result tuple per group, there is
  no need to call end_send_group, instead we have to call end_send as for a regular quick select.
sql/sql_select.h:
  simple_pred is re-used in opt_range.cc

  Added a case for bug #4976 when one of the inner tables is empty.
select.result, join.result:
  Reversed the previous change of the erronious fix for bug #4976.
sql_select.cc:
  The previous fix for bug 4976 was reversed as it
  erroniously converted an outer join into an innner join
  when on_expression does not refer to outer tables.
  This is not valid if inner tables return an empty set.
  Setting dependency on outer tables was added for the above cases.
  To fix the crash in the test case of bug #4976  
  a guard was added that blocks running the crashing code for
  nested outer joins.
