Internal Compiler Error when trying to compile openpgp npm module

See original GitHub issue
curl -O https://unpkg.com/openpgp@4.0.0/dist/openpgp.js
npx google-closure-compiler --js=openpgp.js --js_output_file=out.js

yields a whole lot of warnings and errors and ultimately fails with

java.lang.RuntimeException: INTERNAL COMPILER ERROR.
Please report this problem.

Simplified repro:

async function SymmetricallyEncrypted_prototype_encrypt() {
  this.encrypted = _crypto2.default.cfb.encrypt(
    (await _crypto2.default.getPrefixRandom()), 
    (await _webStreamTools2.default.readToEnd()));
};

Seems to be related to having the two different awaits in one expression, as we rewrite await to yield.

Lets pick this up after the transpilation is moved after type checking.
