Summary: Before this patch, we only collected virtual nodes in NodeRegions, because NodeRegions are only needed to implement ReactCompoundView.reactTargetForTouch() which is only interested in virtual nodes. In the next patch, FlatViewGroup will implement ReactCompoundViewGroup interface which requires knowledge of both virtual and non-virtual children. As a step towards that, we need to include non-virtual nodes in NodeRegions. This patch is implementing that. By itself, it should have not cause any changes in application behavior: we add non-virtual nodes to NodeRegions and mark them as non-virtual, then skip all non-virtual nodes in reactTagForTouch().
