a085cd431d Adjust event times after a PPC clock change 
This likely doesn't change much, but it makes events trigger at the
correct time after a clock change.

fb5537213a CoreTiming: Document initial startup behavior 
Events don't update the downcount until after the first Advance(),
thus Advance() must be called once before scheduling works normally.

aa16282516 Core: Change CoreTiming event key from int to EventType* 
Replace 'int' keys with something that carries type information.
Performance is neutral.

3443a10030 CoreTiming: Merge ScheduleEvent variants into one function 
Now Core::IsCPUThread() only gets called once when using the AnyThread
variant. Also, I think the enum approach makes calling code clearer.

47c8bb26f8 Remove Immediate variants of ScheduleEvent 
Usage of these are replaced with regular equivalents in order
to avoid executing event handlers in the middle of JIT blocks.

4c5f8f9c91 CoreTiming: Drop ProcessFifoWaitEvents. 
globalTimer is only written in Advance, so this function has no function.

5e50c37c13 Alternative fix: promote cycleslate to an s64 everywhere. 
Also changed a few functions to be static.

27beef1ff4 Store an inverted copy of lastOCfactor. 
The inverse operation is more common, especially when games check the
timer rapidly. So we do the division once and store the inverted copy.

67dc26cf1d CoreTiming: Fix 31bit overflow for events scheduling. 
Events scheduled more than 4.12 seconds in the future (2.96 seconds for
Wii games) would overflow the sign bit and get scheduled in the past
instead, causing them to fire instantly.

2ebbfd6f85 Adjust cycle counts so they are accurate to the jit block level 
Previously GlobalTimer was only updated at the end of each slice
when CoreTiming::Advance() was called, so it could be upto 20,000
cycles off.

This was causing huge problems with games which made heavy use of
the time base register, such as OoT (virtual console) and Pokemon
puzzle.

I've also made it so event scheduling will be accurate to the jit
block level, instead of accurate to the slice.

a40ae6883a Move CoreTiming::downcount to PowerPC::ppcState. 
This isn't technically the correct place to have the downcount variable, but it is similar to what PPSSPP does to gain a bit of extra speed on ARM.
We access this variable quite a bit, with each exit in a block it is subtracted from.
On ARM this required four instructions to load and store the value, while now it only requires two.

This gives an average of 1FPS gain to most games.
Examples:
Crazy Taxi: 54FPS -> 55FPS
Luigi's Mansion: 20FPS -> 21FPS
Wind Waker(Save Screen): 27FPS -> 28FPS

This seems to average a 6mhz to 16mhz CPU core emulation improvement in the few games I've tested.

a82675b7d5 Kill off some usages of c_str. 
Also changes some function params, but this is ok.
Some simplifications were also able to be made (ie. killing off strcmps with ==, etc).
