[PATCH] D86612: [libunwind] Enable the SEH unwinding codepaths if building in MSVC mode

compnerd added a comment.

I don't think that this is entirely true.  I believe it is possible to disable SEH with cl, so I think that it is better to conditionalize it as `if defined(__SEH__) || defined(_SEH)` since IIRC, `_SEH` is the define that `cl` uses.
