<pre>Autogenerated IDBFactory.open() does not allow `undefined` for the second argument
The IDL looks like this:
[CallWith=ScriptExecutionContext, RaisesExceptionWithMessage] IDBOpenDBRequest open(DOMString name, [EnforceRange] optional unsigned long long version);
The generated code does the following:
1 - Checks to see if there's exactly 1 argument.
2 - If so, it calls IDBFactory::open(ScriptExecutionContext&, const String& name, ExceptionCodeWithMessage&);
3 - If there is more than one argument, it gets the second argument and converts it to a uint64_t with a range check.
4 - If the conversion failed, it throws an exception for the EnforceRange - "NaN is outside the range 0..2^64-1"
Instead, at step 3, it should allow an explicit "undefined" and call the first form of IDBFactory::open() from step #2</pre>
