According to the spec[1][2], the range quantifier (/a{n,m}/) allows values for n and m up to
2^53 - 1. However, the current JSC does not allow numbers larger than UINT_MAX, so it throws a
SyntaxError:
```
new RegExp("a{9007199254740991}", "u");
// SyntaxError: Invalid regular expression: number too large in {} quantifier
