await and promise

[Mark Volkmann]

I have seen that in Mocha tests, but this code looked different to me.
I'm looking at
https://github.com/google/traceur-compiler/blob/master/test/feature/AsyncFunctions/AlphaRenaming.js
.
I thought to use done in a Mocha test you have to have a parameter named
"done" in the test function.
I suppose I was wrong about that.
