To support arm64, objtool will need to be able to decode aarch64
instructions. This patch series adds some instruction definitions needed
by objtool and moves out encoding/decoding functionalities that do not
rely on kernel code in order.
I'll post the start of the arm64 objtool backend shortly.
Thanks,
Julien
