Monty af7a22d2fa MDEV-31501 Assertion `cond_selectivity <= 1.000000001' failed (actual value 1.125) 
The problem was that because there was no good indexes for the lineitem
table make_join_select() tried to do a last attempt to find a usable key
and called test_quick_select().
test_quick_select() found an index with fewer matching rows then every
before and that caused a problem in get_range_limit_read_cost(),
which assumes that 'best_rows' is the minium rows matched when all
conditions has been taken into account and thus smaller than rows found
in the range.
Fixed by adjusting best_rows to the least rows in any index after
test_quick_select() has been called.
