Fix alignment of generated UNWIND_INFO structures

I missed a few parts of the Windows documentation:

> The UNWIND_INFO structure must be DWORD aligned in memory.

> For alignment purposes, this array [unwind codes] always has an even
> number of entries, and the final entry is potentially unused. In that
> case, the array is one longer than indicated by the count of unwind
> codes field.

This didn't seem to have any practical effect (unwinding tests worked
as-is), but I noticed this while rewriting some handwritten codes.
