NOTE: This work is not yet fully complete; kernel is done, but it was taking an exceedingly long time to get through libstratosphere. Thus, I've temporarily added -Wno-error=unused-result for libstratosphere/stratosphere. All warnings should be fixed to do the same thing Nintendo does as relevant, but this is taking a phenomenally long time and is not actually the most important work to do, so it can be put off for some time to prioritize other tasks for 21.0.0 support.
