In HTMLSelectElement and HTMLOptionsCollection,
indexed setter remove the named element if JS value is null or undefined.
https://code.google.com/p/chromium/codesearch#chromium/src/third_party/WebKit...

I think checking null/undefined in webcore layer is not special for
HTMLSelectElement and HTMLOptionsCollection,
so I added isValueNull and isValueUndefined parameter to all generated
indexed/named property setters.

This is dirty...

How do other browsers behave?

If we need to add these parameters, can we use optional parameters?

     if (!result)
         return v8Undefined();
     return value;
