MDEV-30082 View definition losing brackets changes semantics of the query and causes wrong result
Item_func_not_all::print() either uses Item_func::print() or
directly invokes args[0]->print(). Thus the precedence should be
either the one of Item_func or of args[0].
Item_allany_subselect::print() prints args[0], then a comparison op,
then a subquery. That is, the precedence should be the one of
a comparison.
