fix for bug #12651 (item of a prepared query allocated on non-permanent
are thus dangling later)
mysql-test/r/ps.result:
test for bug #12651
(data allocated on thd's arena but not on permanent arena)
mysql-test/t/ps.test:
test for bug #12651
(data allocated on thd's arena but not on permanent arena)
sql/sql_base.cc:
if there is tree transformation then backup the current arena
and use permanent one (for PS) otherwise the data will be deallocated
after the prepare process is finished.
this bug was introduced with the recent natural join patch
