This finally annoyed me enough to do something about it, I foolishly started
pulling the string and now here I am.

I think the end result is sufficiently more readable to justify the churn. I
particularly like that we now have EXCEPTION_PROLOG_0/1/2.

It will cause some pain for backports, but Nick plans to rewrite the exception
vectors entirely at some point so this will be trivial in comparison.

Yeah I have no problem with this series. I'll get onto that rewrite
again soon.
