MDEV-34055 Assertion '...' failure or corruption errors upon REPAIR on Aria tables
The problem was two fold:
- REPAIR TABLE t1 USE_FRM did not work for transactional
Aria tables (Table was thought to be repaired, which it was not) which
caused issues in later usage of the table.
- When swapping tmp_data file to data file, sort_info files where not
updated. This caused problems if there was several unique keys and
there was a duplicate for the second key.

MDEV-23878 Wrong result with semi-join and splittable derived table
Due to this bug a wrong result might be expected from queries with
an IN subquery predicate in the WHERE clause and a derived table in the
FROM clause to which split optimization could be applied.
The function JOIN::fix_all_splittings_in_plan() used the value of the
bitmap JOIN::sjm_lookup_tables() such as it had been left after the
search for the best plan for the select containing the splittable
derived table. That value could not be guaranteed to be correct. So the
recalculation of this bitmap is needed to exclude the plans with key
accesses from SJM lookup tables.
