Improve optimizer (#660) 
Although it's quite naive at the moment, I added two optimization passes.

Fix version of regenerator-runtime (#644) 
7.7.7 is version of @babel/runtime, not regenerator-runtime. Looks like
the intended version was "0.11.0" as you can see in the yarn.lock:

    regenerator-runtime@^0.11.0:
      version "0.11.1"
      resolved "https://registry.yarnpkg.com/regenerator-runtime/-/re...

55c0258017 Remove empty expression in expression statement with top level await (#630) 
Eats the semi-colon.

This doesn't compile (edit: doesn't compile the code in the tests) though because the target of that folder is ES2015. Also, this is kind of strange for me to put the tests in the "typescript" folder. Should we create something more general?

You can take over this PR if you'd like!
