"In the degenerate case of a top level declaration, “private” and “fileprivate” are the same thing, 
since the scope that “private” refers to is the whole file. “ -Chris Lattner

Since private at the top level means fileprivate, 
it makes sense that the nested declarations of top level fileprivate default to fileprivate.

The only thing that was a little confusing for me was to allow top level private (since it is the same thing as fileprivate)
 but I think it is something once you learn it then it will make sense. (Maybe just hard to explain though)

+1 I am on board. I do not think this needs full review.
