Removing Used_tables_and_const_cache from "class udf_handler".

Browse Source 
It was used only temporary, during udf_handler::fix_fields() time,
and then copied to the owner Item_func_or_sum object.
Changing the code to use the Used_tables_and_const_cache part
of the owner Item_sum_or_func object directly.
