* Add dev command for building wasm backend
This aims to reduce the time spent building when testing with the wasm
backend. On my machine `yarn release` takes 20s while `yarn dev` takes
just 2s.
* Separate out building wasm
* add js interop testing
* checkout specific commit + fix bug in if stmt
* implement suggestions
* add to travis
* friendly error message + fix inverted if
* more intuitive order
* Fix benchmarks using text
* CI: change --all to --all-targets
--all is a deprecated alias to --workspace where we also want to build
all targets: benches, tests, examples etc.
* Add failing alignment test case
* Add wasm-pack test to ci
* Box im_rc::Vector contents to satisfy alignment
This makes the frontend not have alignment issues on 32 bit
architectures (e.g. wasm32-unknown-unknown). The box provides a
consistent alignment for the Vector.
