OK jeremy@
Note that Ruby 3.3 has code to handle BTI in the arm64 coroutine:
https://github.com/ruby/ruby/blob/v3_3_3/coroutine/arm64/Context.S
Hopefully someone can figure out why that doesn't work on OpenBSD,
and how to fix it, so I can work on upstreaming support (as I
upstreamed support for IBT on amd64).
Thanks,
Jeremy
