Hmm, the performance here looks a little worse than #41003 on material-ui and monaco, but that makes me wonder if there were previously more incorrect instantiations in material-ui that just went unnoticed 🤔. The difference is almost within the margin of error, so maybe not too bad...

It's possible the slowdown is just a result of reduced monomorphism in object layouts, but the numbers are higher enough that likely there are more type objects being allocated. Would be interesting to know where those extra allocations are coming from. I have a sense it isn't just spreads in object literals.

I'll see if I can find out—in my first attempts I had some code that used the cache both the old way and the new way and hit a debugger statement any time the results differed. I'll bring that back and see what I can find.

I think I see what's causing the slowdown. The changes aren't quite right for deferred type references, we need to obtain the "root" deferred type reference (the one produced by getTypeFromTypeNode) and then store the cache there. As it currently stands the caching is spread out over multiple type objects when we're doing instantiations of instantiations. In material-ui this causes the type count to increase from 159.5K to 165K. I'll put up a fix shortly.
