RFR: 8370198: Test gc/arguments/TestShrinkHeapInSteps.java crashed: assert(left >= right) failed: avoid underflow [v2]

[Albert Mingkun Yang]

> Add an early-return for outside-heap address in `CollectedHeap::is_in` API.
> 
> While investigating this failure (JDK-8370198), I realized that some java-threads (compiler-threads) in `native` state can invoke `CollectedHeap` APIs. Since heap-resizing occurs inside safepoint but java-threads in `native` state just ignore safepoint, I have added some assert to catch such dangerous uses, where the return value might not be stable.

> Test: tie1-5; can't reproduce the JDK-8370198 with or without this patch for >8000 runs.
