Tracking issue for panic::propagate

[sfackler]

panic::propagate triggers a panic without invoking the panic handler or wrapping the payload in a Box<Any>, allowing for panics to be recovered from at an FFI boundary, transported back into Rust and restarted.

🔔 This issue is now entering its cycle-long final comment period for stabilization in 1.9 🔔

The name of this function likely wants to closely consider the naming of panic::recover of course!

The libs team discussed this during triage yesterday and the decision was to stabilize with the name resume_unwind
