    Description

      After these 2 commits

      MDEV-41632 UPPER(key_col) IN (constant subquery) returns incorrect row
      MDEV-41251 Wrong result with split materialized query

      all remaining calls to Item::deep_copy are used for pushdown purposes.

      Lets rename deep_copy to pushdown_copy
