Vector stores Expression object as OwnPtr instead of raw pointer in XPath.

Currently, Vector has a bug as follows
Vector<OwnPtr<Foo> > foo1;
Vector<OwnPtr<Foo> > foo2 = foo1; <- compile error.

So default parameter is impossible.

I'll fix it in another CL.

+        Function* createFunction(const String& name);
+        Function* createFunction(const String& name, Vector<OwnPtr<Expression> >&);
