Auto merge of #42631 - malbarbo:wasm32, r=alexcrichton

Add a travis builder for wasm32-unknown-emscripten

This commits add an entry to travis matrix that will execute wasm32-unknown-emscripten tests suites.

- Emscripten for asmjs was updated to sdk-1.37.13-64bit
- The tests are run with node 8.0.0 (it can execute wasm)
- A wrapper script is used to run each test from the directory where it is (workaround for https://github.com/kripken/emscripten/issues/4542)
- Some tests are ignore, see #42629 and #42630
