E.g. with a 16k or 64k aarch64 guest kernel, we still have TARGET_PAGE_SIZE at
4k, so all
guest pages are "large", and so run into our current behaviour of flushing the
entire tlb
too often.
Even without that, I expect further cleanups to improve performance, we're just not
there yet.

Does merging pages over a given range be something we could benefit from too? In this
case, entries in our tlbtree would have varying size, allowing us to cover more space with
a single entry.
I don't know. I kinda doubt it, because of tlb flushing mechanics.
But we shall see once everything up until that point is done.
