-ProcessCpuClock was used to check for events that don't need to be checked that often (auto-switch disk + auto fast-forward options). This has been moved to an EndFrame callback.
-This was even slower than intended because of the call to _emu->GetFrameCount() which was, relatively speaking, fairly slow. To improve its performance (since it's used rarely for some things like turbo button processing), a separate GetFrameCount function was added on all console classes, and Emulator::GetFrameCount was also optimized to be faster when called from the emulation thread.
When the auto-switch disk option is enabled, this can improve performance by about 25-30%. When the option is not enabled, this still improves performance by 4-5%.
* SNES: Clear _rumbleData when the rumble controller is latched
The rumble controller spec document states the 16-bit shift register
should be cleared when the P/S Out line goes high and then low.
This behaviour has been verified on a Limited Run Games rumble
controller with a custom test ROM.
