## Summary `fastAddProperties` has shown some perf benefits when used for creating props payload for new components. In this PR we'll try to use it for diffing props for existing components. It would be good enough if it simply doesn't regress perf. We'll be able to delete the old `addProperties`, and make `fastAddProperties` the default behaviour. ## How did you test this change? ``` yarn lint yarn flow native yarn test packages/react-native-renderer -r=xplat --variant=false yarn test packages/react-native-renderer -r=xplat --variant=true ```
