    This commit introduces support for writing unwinding tables in the
    .eh_frame format, to be inserted in the jitdump read by Linux perf and
    emitted with FLAG_perf_prof and FLAG_perf_prof_unwinding_info enabled.
    
    x64 is fully implemented and tested, arm and arm64 are untested and the
    unwinding information needs to be expanded, but the mechanism is ready.
