Source/JavaScriptCore:
This patch is implementing BigIntConstructor and BigIntPrototype
following spec[1, 2]. As addition, we are also implementing BigIntObject
warapper to handle ToObject(v) abstract operation when "v" is a BigInt
primitive. With these classes, now it's possible to syntetize
BigInt.prototype and then call "toString", "valueOf" and
"toLocaleString" when the primitive is a BigInt.
BigIntConstructor exposes an API to parse other primitives such as
Number, Boolean and String to BigInt.
We decided to skip parseInt implementation, since it was removed from
spec.
