    IMPALA-5018: Error on decimal modulo or divide by zero
    
    Before this patch, decimal operations would never produce an error.
    Division by and modulo zero would result in a NULL.
    
    In this patch, we change this behavior so that we raise an error
    instead of returning a NULL. We also modify the format of the decimal
    expr tests format to also include an error field.
    
    Testing:
    - Added several expr and end to end tests.
