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
