This is second attempt (first was #8803 and was incorrect, I definitely should run tests)
Fixes facebook/metro#429 for example.
Yes here is #8787, but I will try anyway. This time I split commits to small chunks. I prefer to eliminate any async/await syntax from file not only because it triggers some strange bugs in v8, but mostly because this syntax is ugly and leads to hard-to-understand code while promise based api is more clean (from my point of view).
