…they Improve the ABI between the panic runtime and libstd * Use the Rust ABI rather than C ABI * Mark some extern functions as safe * Move `PanicPayload` from libcore to liballoc and directly reference `Box<dyn Any>` instead of `*mut dyn Any` * Avoid an unnecessary allocation with panic=abort Follow up to rust-lang#160440
