This pull request is meant to illustrate the RFC proposal to improve control flow integrity for compiled WebAssembly code by using the Pointer Authentication extension to the Arm instruction set architecture (bytecodealliance/rfcs#17), so it is not in a shape to be merged yet. The generation of the unwinding information is a hack to make things work (i.e. pass the tests) before there is a resolution to gimli-rs/gimli#130 and gimli-rs/gimli#608.

P.S. Actually I apply another hack to test the code - I change the processor feature detection logic in
cranelift/native/src/lib.rs, so that the availability of PAuth is hardcoded (and there is no need to use a nightly toolchain). What you see here and what CI is testing is the clean code, though.
