Description

We should use or return the new native BigInt types whenever it's available.

• Use the native BigInt to convert/stringify i64s/u64s
• Support the BigInt type in element comparator and indexOf()
• Add zero-copy toBigInt64Array() and toBigUint64Array() methods to Int64Vector and Uint64Vector, respectively
