"Early NULL-values filtering for ref access" (attempt2+post-review fixes)
1. update_ref_and_keys() accumulates info about null-rejecting
predicates in in KEY_FIELD::null_rejecting, add_key_part saves
these to KEYUSE.
2. create_ref_for_key copies them to TABLE_REF.
3. add_not_null_conds adds "x IS NOT NULL" to join_tab->select_cond of
appropiate JOIN_TAB members.
Includes code cleanups:
* add_key_field() params: s/COND/Item_func/ (as only Item_funcs are
passed to it)
* add_key_fields() params: JOIN_TAB *stat removed (wasn't used)

sql/sql_select.cc:
A fix (bug #9401: type_timestamp segfaults mysqld).
1. create_tmp_field_from_field() is modified to take 'Item_ref *item' and 'char *name'
instead of 'bool modify_item' and 'Item *item'.
2. For Item_sum_min/max we should never modify item, so NULL is
passed as item to the create_tmp_field_from_field().

there was no check of result of
