Description
#### Feature
Support generation of [ORC](https://www.kernel.org/doc/html/latest/x86/orc-unwinder.html) unwind info. This format has somewhat recently been introduced as alternative to frame pointer based unwindingvfor use in the linux kernel.
#### Benefit
ORC is much simpler than DWARF unwind tables. This allows for a simpler and more robust unwinder. Wasmtime could for example use it for unwinding through wasn code as alternative to libunwind.
