[PATCH] D77936: [Windows SEH] Fix abnormal-exits in _try

[Eli Friedman via Phabricator via cfe-commits]

I'm not concerned about the performance implications of whatever approach we take here.  In the worst case, an "icmp+zext" corresponds to two extra arithmetic instructions; that's not enough to matter.  And I expect usually it'll get optimized away.

I'd prefer to avoid exposing our cleanup numbering to user code, if possible.  The Microsoft documentation says it returns 0 or 1.
