CALCITE-6702: Strong Policy for the `SqlStdOperatorTable.POWER` Function is wrongly assigned `AS_IS` when it should be `ANY`. **Context:** In various SQL db implementations, the `POWER(a, b)` function returns `NULL` when either or both operands are null. ``` SELECT POWER(NULL, 2) AS "ALIAS1"; -- => Returns NULL SELECT POWER(2, NULL) AS "ALIAS2"; -- => Returns NULL SELECT POWER(NULL ,NULL) AS "ALIAS3"; -- => Returns NULL ``` These are all the cases I could think of:  This means that the correct null policy for the `POWER` function is `ANY` instead of `AS_IS`, since this expression is `NULL` **if and only if** at least one of its arguments is `NULL`. -- This is an automated message from the Apache Git Service.
