Waiting for a background thread to finish a task isn't going to
work when there are no background threads. Luckily, we can sidestep
the problem by compiling with Turbofan immediately, instead of
triggering dynamic tier-up through repeated execution. As a nice bonus,
this makes the test faster in non-predictable modes too.
