Failing wasm tests

[calebzulawski]

I tracked down the cause of the wasm test failures and it looks like it's due to the comparison ops added to tests in #80. It looks like wasmparser has been updated to support these opcodes so it's just a matter of the changes propagating to wasm-bindgen-test. I opened rustwasm/wasm-bindgen#2522 to track this.

I think we can just ignore the failures for now and they should start passing against once wasm-bindgen-test is updated.

I would like to find all the wasm tests that are currently failing on Chrome and disable them individually, but that might be asking too much.

This currently hinges on rustwasm/wasm-pack#998
To fix this we can either update our tests to no longer depend on using the wasm-pack binary, or wait.
I opened #96 to temporarily omit the wasm SIMD test suite in the meanwhile.

This actually was waiting for wasm-bindgen-cli to do an actual release, as it turns out. As Travis is broken, I will move the relevant wasm CI to GHA when I patch the tests back in and force an appropriate minimal wasm-bindgen version.
