      Description

      This mdev is about leveraging long unique index for blob in optimizer.

      Currently there are 2 approaches

      1. fix ha_index_read_max(idx_map) to look for hash(blob column ) instead of actual blob.

      2. Extend the where condition with DB_ROW_HASH_XX = hash(where long columns)
