Subject: WL#2985 "Partition Pruning": post-review fixes: - Added more
 comments. - Added a RANGE_OPT_PARAM::remove_jump_scans flag that disables
 construction of index_merge   SEL_TREEs that represent unusable conditions
 like "key1part1<c1 OR key2part2<c2" - make prune_partitions() function handle
 the case where range analysis produces a list of   index_merge trees (it
 turned out that this is possible, appropriate test case added). - Other small
 fixes.
