[PATCH] D43744: [WebAssembly] Fix rethrow's argument type

[Derek Schuff via Phabricator via llvm-commits]

I forget what the spec says right now, but I think we will need a null value for except_ref in the spec anyway, because locals are implicitly initialized to their respective 0 values. So we'd need a corresponding 0 value for ref types. So I think it would be fine to have a nullref type in LLVM too.
