      Description

      The "SegmentPruner" can check whether a segment can be skipped or not by checking the min/max dimension value with the "where " conditions.

      While, the currentĀ "SegmentPruner" only checks the simple logic condition ("COL=X") or "AND" conditions. This means, if there is a "OR" condition, Kylin will not check the sub-conditions.

      ThisĀ  change is to add the support for checking sub-conditions under "OR".
