          Description

          After a set of patches made under terms MDEV-7950, Item_func::select_optimize() and Item_func::optimize_type have now a very little sense.

          select_optimize() is now used only in Item_func::get_mm_tree().

          We just need to split Item_func::get_mm_tree() into:

          • a non-optimized default implementation for Item_func::get_mm_tree(),
          • an optimized implemetation for Item_bool_rowready_func2::get_mm_tree()
          • an optionally optimized implementation in Item_func_like::get_mm_tree().
