Merge #530

530: Improved clarity on tests r=syrusakbary a=syrusakbary Improved clarity on tests. * This PR improves the [Makefile making it much easier to test and readable](685ed53070/Makefile). * It also assumes we are building always with `+nightly`, so the cache can be reused in the CI. * It improves the testing section in the [main README](685ed53070/README.md (testing)) Co-authored-by: Brandon Fish <brandon.j.fish@gmail.com> Co-authored-by: Syrus <me@syrusakbary.com>

 ## Testing

 Thanks to [spec tests](https://github.com/wasmerio/wasmer/tree/master/lib/spectests/spectests) we can ensure 100% compatibility with the WebAssembly spec test suite.

-If you need to regenerate the Rust tests from the spec tests

+Each backend can be tested separately:
