I don't think this one will actually affect the size, since we're going
From 27 to 23 bits before the array of structs.

However, these changes all look good to me.  Series is:

I think that moving the cache key to the context is a really good idea.
Back when I did this work, we still had non-shader-based hardware as a
significant concern, but I don't think we particularly care about
optimizing for those any more.  They could just maintain the ff state
key and as statechanges happen but never consume it.
