Bug #22085 Crash on the execution of a prepared statement using aggregating IN subquery

Description:
An execution of a prepared statement that uses an IN subquery with aggregate functions in the having clause may cause a server crash.

This bug happens by similar reasons that bug #21493 for the code 5.0 line.
Currently IN subqueries are transformed into EXIST subqueries.
If a subquery is aggregating this transformation results in
modification of the HAVING clause. This transformation is valid for
any execution of the prepared statement and is performed on
the statement memory. At the same time the presence of aggregate functions
in the HAVING clause triggers a modification of it, but by some reasons,
it's done on the execution memory. The current 4.1 code performs this
modification before the subquery transformation.
As a result we have object created on the execution memory that refers to 
objects on the statement memory.

  Fixed bug #22085: Crash on the execution of a prepared 
  statement that uses an aggregating IN subquery with 
  HAVING clause.
  A wrong order of the call of split_sum_func2 for the HAVING
  clause of the subquery and the transformation for the 
  subquery resulted in the creation of a andor structure
  that could not be restored at an execution of the prepared
  statement.
