RFR: 8374622: StressIncrementalInlining should also randomize the processing order [v2]

[Marc Chevalier]

> As it says: randomize the order the late inlines are processed, and slightly factor it with macro nodes.
> 
> I didn't add shuffle to the `GrowableArray` class since it seems a bit method specialized method (and it seems it'd be a controversial change to a widely use class), it would make `GrowableArray` depends on `Compile` for random number generation (or require a callback, for instance, giving a non-trivial signature and usage), I couldn't find other shuffling of such an object.
> There is also shuffling of `UniqueNodeList` (for `StressIGVN`), but it seems hard to unify: access and length are not written quite the same, it would probably be not simpler than duplicating the implem (which is simple, so it's fine in my opinion).
