Probably it can be looked up although it would require incrementing the field_iterator until it reaches the last non-static data member of the record.

I don't think there is a way to do that reliably. The FieldDecl for the array isn't always available in struct LValue, as far as I can tell, so it looks like we'll need a bit here.
