[dev.typeparams] cmd/compile/internal/types2: handle untyped constant arithmetic overflow
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.
