machenbach 86bd2b3c23 Revert of Disable non-standard Promise functions in staging (patchset #5 id:80001 of https://codereview.chromium.org/1469543003/ )
Reason for revert:
[Sheriff] This breaks ignition on arm sim debug:
https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20arm%20-%20sim%20-%20debug/builds/5317

Seems to not be caught by the cq bot that builds release with dchecks.
