Inputs are slower to update than other tags

If you compare:

to this one where I've swapped out the input for a span:

then you'll notice the second one is about twice as fast to update. Maybe we can optimize ReactDOMInput to bring these more in line?

I had a comment a long time ago (it might still be relevant). We shouldn't be reading from the DOM in order to reconcile because that's kind of the point of reconciling - to be able to detect changes without having to resort to touching the DOM. Not sure if it's possible to do the types of things we want without resorting to DOM touching.

We'll keep doing perf work but this doesn't need to stay open as a separate issue.
