Unless I am blind this handles only x86-style stack handlers, and not
the function tables similar to amd64 that are likely to be present as
well on arm64. Though I guess because of the lack of arm64 compilers,
documentation and binaries from Microsoft we don't really know how
Windows (will) handle arm64 exceptions.
