Enables building and running Cemu natively on Windows on ARM (e.g. Snapdragon devices) with clang-cl. The existing AArch64 recompiler backend is used, so no x64 emulation is involved. Build system (CMakeLists.txt, dependencies/ih264d, src/Cafe): - Auto-select the arm64-windows-static vcpkg triplet and detect the AArch64 architecture even when the emulated host shell misreports it. - Disable IPO for clang-cl (LTO would force lld-link, which cannot read vcpkg's MSVC /GL objects) and link clang_rt.builtins for the compiler-rt calls (e.g. __udivti3) that lld-link does not add. - Set the static CRT on the xbyak_aarch64 target. - Locate pkgconf under the actual vcpkg host triplet instead of a hardcoded x64-windows path. - Build the bundled ih264d decoder as portable C on ARM64/Windows; its NEON .s files use ELF-only :got: relocations that do not assemble for COFF targets. Source (precompiled.h, ExceptionHandler_win32, Debugger, LatteTextureCache): - Guard x86-only intrinsics/paths behind ARCH_X86_64. clang-cl defines _MSC_VER but not __GNUC__, so several `#if defined(_MSC_VER)` branches wrongly selected x86 intrinsics on ARM64. Adds AArch64 register dumping to the crash handler. Manifest: use processorArchitecture="*" for Common-Controls so it resolves on ARM64. See BUILD.md for the build steps (Ninja + clang-cl + -DCMAKE_LINKER_TYPE=MSVC). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
