  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 )

  1. Let inputString be ? ToString(string).
