`shouldBeRef` incorrectly assumed that all `throw_ref`s within a `catch` body had been generated from `rethrow`s, which was not true, because `throw_ref`s are also created when translating `try`-`delegate`s: https://github.com/WebAssembly/binaryen/blob/219e668e87b012c0634043ed702534b8be31231f/src/passes/TranslateEH.cpp#L304 This fixes the assumption and changes `cast` to `dynCast`.
