      Description

      Currently deleteMergeQualifiers() is not idempotent. If two GCMulitpleMergedRegionsProcedures are run for the same merged child region, the second run will delete the row for the merge region from meta table and leave a hole. It needs to make sure it only deletes columns with merge qualifiers.
