Heejin Ahn 9f770b36cb [WebAssembly] Fix catch unwind mismatches ...

This fixes unwind destination mismatches caused by 'catch'es, which
occur when a foreign exception is not caught by the nearest `catch` and
the next outer `catch` is not the catch it should unwind to, or the next
unwind destination should be the caller instead. This kind of mismatches
didn't exist in the previous version of the spec, because in the
previous spec `catch` was effectively `catch_all`, catching all
exceptions.
