Subject: [PATCH] Remove empty expression in expression statement with top
 level await (#630)

Eats the semi-colon.

This doesn't compile 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!
