[WebAssembly] Misc. fixes in cfg-stackify-eh.ll
- Fix `preds` comments - Delete nonexistent attributes in instructions (They used to exist in clang-generated files, but I removed most of them to make the tests tidy. We have only `nounwind` and `noreturn` left here.) - Add missing `Function Attrs` comments in function declarations None of these affect test function semantics or test results for now.
