> Add support for SAFE_MULTIPLY in BigQuery.
> SAFE_MULTIPLY: Equivalent to the multiplication operator '*', but returns NULL if overflow occurs.
> Example #1: {{SELECT SAFE_MULTIPLY(3, 4)}} would return {{12}}.
> Example #2: {{SELECT SAFE_MULTIPLY(2^63, 2)}} would return {{NULL}} because of overflow.
