JIT optimizations and refactoring (#675) 
* CPU/Recompiler: Use rel32 call where possible for no-args

* JitCodeBuffer: Support using preallocated buffer

* CPU/Recompiler/AArch64: Use bl instead of blr for short branches

* CPU/CodeCache: Allocate recompiler buffer in program space

This means we don't need 64-bit moves for every call out of the
recompiler.

* GTE: Don't store as u16 and load as u32

* CPU/Recompiler: Add methods to emit global load/stores

* GTE: Convert class to namespace

* CPU/Recompiler: Call GTE functions directly

* Settings: Turn into a global variable

* GPU: Replace local pointers with global

* InterruptController: Turn into a global pointer

* System: Replace local pointers with global

* Timers: Turn into a global instance

* DMA: Turn into a global instance

* SPU: Turn into a global instance

* CDROM: Turn into a global instance

* MDEC: Turn into a global instance

* Pad: Turn into a global instance

* SIO: Turn into a global instance

* CDROM: Move audio FIFO to the heap

* CPU/Recompiler: Drop ASMFunctions

No longer needed since we have code in the same 4GB window.

* CPUCodeCache: Turn class into namespace

* Bus: Local pointer -> global pointers

* CPU: Turn class into namespace

* Bus: Turn into namespace

* GTE: Store registers in CPU state struct

Allows relative addressing on ARM.

* CPU/Recompiler: Align code storage to page size

* CPU/Recompiler: Fix relative branches on A64

* HostInterface: Local references to global

* System: Turn into a namespace, move events out

* Add guard pages

* Android: Fix build

 2020-03-27 01:42:59 +10:00
Connor McLaughlin 08ad5aad53 SPU: Run muted voices when IRQ is enabled

interrupts are not used by completely ignoring muted voices in those.
 2020-03-27 01:42:43 +10:00
Connor McLaughlin 18cc3d5932 SPU: Stub out external volume registers 
If nothing else, it'll avoid spamming the log.
 2020-03-24 00:22:02 +10:00

Fixes muted audio in Michelin Rally Masters.

Connor McLaughlin 4c2597acf3 SPU: Process key on/off at next 44100hz cycle 
Some games, particularly CART World Series and Monkey Hero, depend on
this behaviour.

Nocash might be incorrect here.

Connor McLaughlin 6a6aa72f3a SPU: Add a tick counter and delay between key on/off writes 
Not yet tested on hardware. We believe that writing to a specific
voice's key on/off register within 2 samples/ticks of the first
write will result in the second write being ignored. This still
needs to be tested on hardware for confirmation.

Thanks to @PSI-Rockin for the idea.

Fixes sound effects in Monkey Hero.
