Comment:

 Mozilla made progress on this and in order to enable that with `--non-
 writable-jitcode` we only need to backport https://hg.mozilla.org/mozilla-
 central/rev/a0dbf1fe665f. Seems to be worth for the next alphas at least.
 We might want to backport
 https://bugzilla.mozilla.org/show_bug.cgi?id=1234246 as well.
