Changes integer rounding to more closely meet the documentation
The documentation explains to round before doing any bounds checks
All this really does is make sure some exception bits won't be set wrong
This depends on the rounding mode, fixing cases such as:
- Round to even, (0x7fffffff, 0x7fffffff.8)
- Round to down, (0x7fffffff, 0x80000000)
This change also uses some standard functions for rounding
Previously using them was casting to an s32 directly, now keeps the f64
RoundToIntegerMode introduced due to roundeven not being part of C++17
Finally, it can change a >0x7fffffff to >=0x80000000, done because:
- It looks nicer now with integers (I liked 0s)
- It gives ever so slightly better codegen on Aarch64

`Layer::Save` only does its thing if the layer has `is_dirty == true`.
But SYSCONF could have been modified by other layers, so if the base layer wasn't made dirty by anything else, then it wouldn't be restored.

I tried making the new templated Interpret callback test only the relevant exceptions (EXCEPTION_DSI, EXCEPTION_PROGRAM, or both), but didn't find a significant performance boost in it. As I am learning, the biggest bottleneck is the number of callbacks emitted, not usually the actual contents of them.
WritePC is now needed far less, only for instructions that end the block. Unfortunately, WritePC still needs to update `PowerPCState::npc` to support the false path of conditional branch instructions. Both drawbacks should be smoothed over by optimized cached instructions in the future.
Use QObject->deleteLater() instead of the delete operator to destroy
child widgets of the layout. This prevents crashes caused by pending
events trying to access the now-destroyed widget.
The player_index field in question is ultimately what gets used to determine which ranks get displayed in the leaderboards chart, and because this was missing the chart was simply displaying the top four results no matter what.
The cause of the leaderboard spam was primarily this call where if there was an attempt to get leaderboard info and there wasn't already, there would be a fetch request. This is bad for many reasons: some games have hundreds of boards that will be fetched at startup, if there's simply no data to populate that board, this will just continue to fetch every time the dialog needs to update. To mitigate this, I simply don't load leaderboard information until there are events for that leaderboard - less information for the player, sadly, but heavily cuts down on the number of leaderboard fetches.
