This is *very* slow. You don't want to enable it if you don't need it.
It is also incompatible with the recompiler and will disable it if the
option is enabled.
* 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
