For bug #168672 I'm updating us to version 0x1 and hacking the version number in the spec tests to 0x1 because spec+wabt isn't ready yet:
I'm updating JSTests/wasm/import-spec-tests.rb a bit to use the new spec directory layout and ignore fail tests. There's more to do: spec tests have substantially changed and now have more than just these "core" tests.
Actually, we should drop wabt and use spec's own JS translator (according to binji).
Though he's updating wabt at my prompting: https://github.com/WebAssembly/wabt/pull/313
