jroelofs created this revision.
Herald added a subscriber: mgorny.
Mostly cargo-culted from libcxxabi, since the unwinder was forked from there in
the first place.
Might still be some cruft that's only applicable to libcxxabi in here, so let
me know if you spot anything like that. I killed some of it, but there could be
more.
