`CollectedHeap::is_gc_active()` is confusing, since its name implies any GC phase is running, while it actually only covers the STW GCs. It would be good to rename it for clarity. The freed-up name, `is_gc_active`, could then be repurposed to track any (concurrent or STW) GC phase running. That would be useful to resolve ~~JDK-8331572~~.

Doing this rename separately guarantees we have caught and renamed all current uses.
