This still needs a comment - e.g. "BookmarkBubble should always try to anchor
TOP_RIGHT, but the LocationBarBubbleDelegateView constructor will infer NONE if
|anchor_view| is null."

Added a comment. Made it more generic w/o describing implementation details of
LocationBarBubbleDelegateView which may change causing this comment to rot.

   if (!anchor_view) {
     bookmark_bubble_->SetAnchorRect(anchor_rect);
     bookmark_bubble_->set_parent_window(parent_window);
