    This reverts commit 8b60d8fc.

    Original change's description:
    > Reland "[cpu-profiler] Log OSR code when starting the profiler"
    > 
    > This is a reland of f6965281
    > 
    > Updated the test:
    > 1. Set profiling interval to 100us to get 10x the samples
    > 2. Guarantee we spend at least 1ms per iteration, instead of only
    > bailing out if we spend more than 1ms. This gives us enough samples on
    > release mode.
    > 3. Increase the time spent profiling optimized code by 50% to make sure
    > we have a big enough difference.
    > 
    > With 1000 iterations I didn't see any flakes locally so this looks solid
    > now.

    > > There is a weak cache of OSR code per native context, so iterate that
    > > on profiler startup and log all the code objects.
