This series of patches is for initial support of Windows 10 on ARM as a QEMU
host.
Currently only TCG intepreter is working correctly, it crashes when TCG JIT is
enabled.
For now we assume it is built using the clang aarch64-w64-mingw32 toolchain,
you can get a prebuilt toolchain at https://github.com/mstorsjo/llvm-mingw.
QEMU_PACKED: Remove gcc_struct attribute in Windows non x86 targets
This attribute is for x86 only, and it generates an warning on ARM64
Clang/MinGW targets.
