Likely a redundant declaration of Item_cache::used_table_map

          Description

          According to these declarations:

          class Item_basic_constant :public Item
{
  table_map used_table_map;
  ...
};
...
class Item_cache: public Item_basic_constant
{
protected:
  Item *example;
  table_map used_table_map;
...
}

          Item_cache has two used_tables_cache, one of which is declared in Item_cache itself, and another one is derived from Item_basic_constant.

          It's very likely that the second declaration is not really necessary.
