Unfortunately, due to most OpenSSL assembly using custom exception
handlers to unwind, most of our assembly doesn't work with
non-destructive unwind. For now, CHECK_ABI behaves like
CHECK_ABI_NO_UNWIND on Windows, and CHECK_ABI_SEH will test unwinding on
both platforms.
The tests do, however, work with the unwind-code-based assembly we
recently added, as well as the clmul-based GHASH which is also
code-based. Remove the ad-hoc SEH tests which intentionally hit memory
access exceptions, now that we can test unwind directly.
Now that we can test it, the next step is to implement SEH directives in
perlasm so writing these unwind codes is less of a chore.
