      Fix for BUG#8877: Implementation of · d0c9b362
      sergefp@mysql.com authored
      "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)
