This ensures that they are accessible to methods like `AtomicIntegerFieldUpdater.newUpdater` no matter which `util.concurrent` class those methods are called from. Previously, we were trying to arrange for those methods to be called from `AggregateFutureState` itself—specifically, through methods like `remainingCountUpdaterFromWithinAggregateFutureState`. However, we're finding that optimizers sometimes inline those methods into callers in other classes, leading to the warning "SafeAtomicHelper is broken!" Rather than try to prevent inlining with `-dontinline` directives, we instead give in and expand the fields' visibility. We already did this for `AbstractFutureState` in cl/742334547, albeit for somewhat different reasons, so we can follow the same playbook here: Rename the fields to make them harder to use by accident (as in cl/741607075), and update our Proguard config for the rename (as in cl/742724817). At that point, we might as well inline methods like `remainingCountUpdaterFromWithinAggregateFutureState` ourselves just to simplify the code, so I've done so. (Note that even `private` fields "should" be accessible to nested classes, thanks to nestmates. However, that's [not the case with `-source 8 -target 8`](https://github.com/google/guava/blob/a429676a3bb68ac9b29cea0f15ae65065bdf5a44/guava/src/com/google/common/util/concurrent/AbstractFutureState.java#L397-L402), and apparently it's not the case for Android, as well, even without `-source 8 -target 8`.) RELNOTES=`util.concurrent`: Modified our fast paths to ensure that they continue to work when run through optimizers, such as those commonly used by Android apps. This fixes problems that some users may have seen since [Guava 33.4.5](https://github.com/google/guava/releases/tag/v33.4.5). (b8dcaed) PiperOrigin-RevId: 744855670
