Some tables where not eliminated when they could have been. This was caused because HA_KEYREAD_ONLY is not set anymore for InnoDB clustered index and the elimination code was depending on field->part_of_key_not_clustered which was not set if HA_KEYREAD_ONLY is not present. Fixed by moving out field->part_of_key and field->part_of_key_not_clustered from under HA_KEYREAD_ONLY (which they should never have been part of). Other things: - Fixed a bug in make_join_select() that caused range to be used when there where elminiated or constant tables present (Caused wrong change of plans in join_outer_innodb.test). This also affected show_explain.test and subselct_sj_mat.test where wrong 'range's where replaced with index scans. Reviewer: Sergei Petrunia <sergey@mariadb.com>
