Initial Linux Aarch64 support * Update asmjit dependency (aarch64 branch) * Disable USE_DISCORD_RPC by default * Dump some JIT objects in rpcs3 cache dir * Add SIGILL handler for all platforms * Fix resetting zeroing denormals in thread pool * Refactor most v128:: utils into global gv_** functions * Refactor PPU interpreter (incomplete), remove "precise" * - Instruction specializations with multiple accuracy flags * - Adjust calling convention for speed * - Removed precise/fast setting, replaced with static * - Started refactoring interpreters for building at runtime JIT * (I got tired of poor compiler optimizations) * - Expose some accuracy settings (SAT, NJ, VNAN, FPCC) * - Add exec_bytes PPU thread variable (akin to cycle count) * PPU LLVM: fix VCTUXS+VCTSXS instruction NaN results * SPU interpreter: remove "precise" for now (extremely non-portable) * - As with PPU, settings changed to static/dynamic for interpreters. * - Precise options will be implemented later * Fix termination after fatal error dialog 2021-12-30 17:39:18 +01:00			`#pragma once`
