GCC: explicitely instantiate JSObject::ApplyAttributesToDictionary for NumberDictionary

elements.cc invokes ApplyAttributesToDictionary using NumberDictionary as its template
parameter. But the declaration of the template method is in js-object.cc, so nobody
can actually compile the version for number dictionary. This is fixed requesting
explicit instantiation for NumberDictionary.

This was breaking GCC build.
