I did this on ncbuffer2 when we were using it for LDN 3, but I noticed that it can apply to the current buffer manager too, and it's an easy performance win.
The only buffer access that can come from another thread is the overlap search for buffers that have been unmapped. Everything else, including modifications, come from the main GPU thread. That means we only need to lock the range list when it's being modified, as that's the only time where we'll cause a race with the unmapped handler.
This has a significant performance improvements in situations where FIFO is high, like the other two PRs. Joined together they give a nice boost (73.6 master -> 79 -> 83 fps in SMO).
* Prune ForceDirty and CheckModified caches on unmap
Since we're now using this for modified checks on the HLE indirect draw method, I'm worried that leaving these to forever gather cache entries isn't the best idea for performance in the long term, and it could keep old buffer objects alive for longer than they should be.
This PR adds the ability to prune invalid entries before checking these caches, and queues it whenever gpu memory is unmapped. It also aligns modified checks to the page size, as I figured it would be possible for a huge number of overlapping over a game's runtime.
This prevents Super Mario Odyssey from having 10s of thousands of entries in the modified cache in Metro Kingdom, and them duplicating when entering and leaving a building (should be cleared, as they were unmapped).
