Eladash 16381929ba vm_var.h: Ensure 16-bytes alignment of gvar
Some PPU instructions require memory to be aligned otherwise they produce different results. I've already seen their usage in cellSaveData disassembly so may as well ensure it for all.

Nekotekina 12c83b340d Remove built_function
With today's branch prediction techniques, it's hardly useful.

Nekotekina 580bd2b25e 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

Eladash 50ad7ba1f6 vm: Fix vm::unmap
* Make vm::unmap atomic, squash the memory unmapping process inside this function while still using the same VM mutex ownership.
* Make vm::unmap not fail due to random vm::get calls, shared_ptr reference count is no longer a condition.
* Fix sys_mmapper_free_address spuriously failing with EBUSY due to random vm::get calls.
* Fix sys_vm_unmap race condition due to non-atomic vm::unmap.
* Add an optional verification block ptr arg to vm::unmap, used by patches.

Eladash b40ed5bdb7
Patches/PPU: Extend and improve patching capabilities (code allocations, jumps to any address) (#10779)
* Patches/PPU: Implement dynamic code allocation + Any-Address jump patches

Also fix deallocation path of fixed allocation patches.

vm: Fix an overflow at vm::alloc, fix vm::find_map (#10760)
* The statement addr += align could have overflowed resulting in either infinite loop or allocating memory outside of the region (illegal).
Add a check checking if it's the last iteration of the loop, then break without adding.

* vm::find_map condition didn't consider the size of the map to be allocated, allowing illegal occupation of [<=0xB000'0000]-0xCFFF'FFFF. (0xC000'0000-0xCFFF'FFFF is reserved for RSX)
