Forbid use of `extern "C-unwind"` inside standard library
Those libraries are build with `-C panic=unwind` and is expected to be linkable to `-C panic=abort` library. To ensure unsoundness compiler needs to prevent a `C-unwind` call to exist, as doing so may leak foreign exceptions into `-C panic=abort`.
