2a3943dbec 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.
