Implement branch target protection using the branch target identification
feature introduced in Armv8.5. This provides "head-CFI" to complement
the "tail-CFI" provided by retguard. Unfortunately most arm64 machines
don't support this feature yet. But Apple M2 does support it and it
seems to work there.
