FindReplacementOrReplaceMaterializedItems()

Item * FindReplacementOrReplaceMaterializedItems	(	THD *	thd,
		Item *	item,
		const Func_ptr_array &	items_to_copy,
		bool	need_exact_match
	)

ReplaceMaterializedItems()

void ReplaceMaterializedItems	(	THD *	thd,
		Item *	item,
		const Func_ptr_array &	items_to_copy,
		bool	need_exact_match
	)

Like FindReplacementOrReplaceMaterializedItems, but only search below the item, ie.

ignore point 2 above. This can be useful if doing self-replacement, ie., we are replacing source items in items_to_copy and don't want to replace an item with its own output.
