If `GetValueAsUnsigned` fails, this will give you an `APSInt` that looks like
0, meaning there's no way to distinguish between a `ValueObject` that
represents 0 and a failure value.
Suggestion: Either return an invalid `APSInt` (via default constructor) or
return a `std::optional<APSInt>` or `llvm::Expected<APSInt>` if you want an
error message back.
