Reason for revert:
Mac gc stress failures:
https://build.chromium.org/p/client.v8/builders/V8%20Mac%20GC%20Stress/builds/11195
There's also this flake, but maybe unrelated:
https://build.chromium.org/p/client.v8/builders/V8%20Win64/builds/15422
Original issue's description:
> [tests] Make assertOptimized()/assertUnoptimized() great again.
>
> The mentioned asserts did not work properly with interpreted and turbofanned functions.
>
> To fix this issue %GetOptimizationStatus() now returns a set of flags instead of a single value.
>
> This CL also adds more helper functions to mjsunit, like isNeverOptimize(), isAlwaysOptimize(),
> isOptimized(fun), etc.
