c443dbff0e Ensure that test_quick_select doesn't return more rows than in the table 
Other changes:
- In test_quick_select(), assume that if table->used_stats_records is 0
  then the table has 0 rows.
- Fixed prepare_simple_select() to populate table->used_stat_records
- Enusre that set_statistics_for_tables() doesn't cause used_stats_records
  to be 0 when using stat_tables.
- To get blackhole to work with replication, set stats.records to 2 so
  that test_quick_select() doesn't assume the table is empty.

6789f2cfab MDEV-18304 sql_safe_updates does not work with OR clauses 
not every index-using plan sets bits in table->quick_keys.
QUICK_ROR_INTERSECT_SELECT, for example, doesn't.

Use the fact that select->quick is set instead.

Also allow EXPLAIN to work.
