03081bc1fd Changed the default setting of the optimizer switch 'optimize_join_buffer_size'. 
Made it 'off' by default.

1492de8563 Set the default to be mrr=off,mrr_sort_keys=off: 
- Set the default
- Adjust the testcases so that 'new' tests are run with optimizations turned on.
- Pull out relevant tests from "irrelevant" tests and run them with optimizations on.
- Run range.test and innodb.test with both mrr=on and mrr=off

b83cb52e9e Backport of subquery optimizations to 5.3. 
There are still test failures because of:
- Wrong query results in outer join + semi join
- EXPLAIN output differences
