BigInt.parseInt ( string, radix )
The parseInt function produces a BigInt value dictated by
interpretation of the contents of the string argument according to
the specified radix.
The algorithm is the same as 18.2.5 but with the following edits:
* For all cases which result in returning NaN, throw a SyntaxError
exception.
* For all cases which result in returning -0, return 0n.
* Replace the second to last step, which casts mathInt to a Number,
with casting mathInt to a BigInt.
18.2.5 parseInt ( string, radix )
[...]
6. Let R be ? ToInt32(radix).
