In json::Value, getAsInteger returns an optional<int64_t> and getAsNumber returns an optional<double>. If a value is larger than what an int64_t can hold but smaller than what a uint64_t can hold, the getAsInteger function will fail but the getAsNumber will succeed. However, the value shouldn't be interpreted as a double. rdar://105556974 Differential Revision: https://reviews.llvm.org/D144238
