Some of the speed hacks were not approved for RetroAchievements, meaning that users had to choose between not getting hardcore achievements, or having poor performance.
Also, renamed the instances of `$Limit internal FPS to VPS (improves performance)` to `$Limit internal frame rate (speed hack)` for consistency. They are enabled by default, so unless the user disabled them, it won't break the configuration.
The patches rearrange some branching to insert a call to VIWaitForRetrace in the main game loop.
This allows ImmediateXFB to work properly so it is no longer forced off by the game ini.
