Summary: @public This is quite a big diff but the actual meaningful change is simple: now we use ShadowView class instead of ShadowNode in mutation instructions. Note: * In some places (especially during diffing) we have to operate with ShadowNodeViewPair objects (which represents a pair of ShadowNode and ShadowView). The reason for that is that we cannot construct child ShadowViews from parent ShadowViews because they don't have any information about children. * `ShadowTree::emitLayoutEvents` is now much simpler because ShadowView better represents the specifics of this kind of object. * The code in RCTMountingManager also became simpler. This change will allow us to implement more cool tricks soon. Reviewed By: mdvacca Differential Revision: D9403564 fbshipit-source-id: dbc7c61af250144d6c7335a01dc30df0005559a2
