Factor out the existing "constant representation" check after untyped constant arithmetic and combine with an overflow check. Use a better heuristic for determining the error position if we know the error is for a constant operand that is the result of an arithmetic expression. Related cleanups. With this change, untyped constant arithmetic reports an error when (integer) constants become too large (> 2048 bits). Before, such arithmetic was only limited by space and time.
