The test code comes from aarch64 mostly, only that it booted as bios in qemu since kernel requires elf format and bios uses binary format. In addition to providing the binary, this patch also includes the source code and the build script in tests/migration/loongarch64. So users can change the source and/or re-compile the binary as they wish.
