Test suite doesn't work with new versions of wabt (assert_return_{canonical,arithmetic}_nan)

4

New versions of wabt reject spec test assertions `assert_return_canonical_nan` and `assert_return_arithmetic_nan` since https://github.com/WebAssembly/wabt/commit/415c3bb1b70c5edc9beb3a7e2cea5d9247e1e52c. This repo still uses those old assertions and doesn't work with current versions of wabt anymore. Ideally...
