Updated, thanks!

It turns out that wasmi doesn't canonicalize NaNs (paritytech/wasmi#19) so I've disabled fuzzing of modules with FP ops for now. If it seems worthwhile, we can add a Config option to wasm-smith for that too, but fuzzing seems to be getting coverage pretty efficiently right now as I watch it run.

This fails the "publish" check because it's using a crate-source patch in the root Cargo.toml for wasm-smith; @fitzgen, would you mind publishing a new version to crates.io?

Sure thing.

Thanks! Updated.

I also just added an experimental_x64 feature flag to the fuzz crate so that we can fuzz the new backend.
