MDEV-6738: use_stat_table + histograms crashing optimizer
...
- When EITS code calls store_key_image_to_rec(), it should follow its
calling convention (which is counter-intuitive)

MDEV-6442: Assertion `join->best_read < double(...)' failed with optimizer_use_condition_selectivity >=3
...
- Fix the crash by making get_column_range_cardinality()
to handle the special case where Column_stats objects
is an all-zeros object (the question of what is the point
of having Field::read_stats point to such object remains a
mystery)
- Added a few comments. Learning the code still.

Fix a trivial typo: in table_multi_eq_cond_selectivity(), reset the loop variable
between loops.
