Log Message:
-----------
[JSC] `BigInt("-")` and `BigInt("0x ")` should throw a `SyntaxError`
https://bugs.webkit.org/show_bug.cgi?id=324127
Reviewed by Marcus Plutowski.
StringToBigInt returned 0n for a string that has only a sign ("-", " + ")
or only a radix prefix followed by white space ("0x "). The spec requires
at least one digit after either of them.
Disallow an empty digit sequence once a sign is consumed, and trim the
trailing white space before checking for it.
