Can we just disable typed arrays and array buffers in this test case as in the
other test cases? Also as with the other test case a short explanation of what
breaks might help. I was thinking along the lines of ...

// Experimental natives are compiled during snapshot deserialization.
// This test breaks because heap layout changes in a way that closure
// is visited before shared function info.

   Heap* heap = isolate->heap();
   HandleScope scope(isolate);
 
   // Perform one initial GC to enable code flushing.
   heap->CollectAllGarbage(Heap::kAbortIncrementalMarkingMask);
 
   // Prepare a shared function info eligible for code flushing for which
   // the unoptimized code will be replaced during optimization.
   Handle<SharedFunctionInfo> shared1;

   DeferredHandleScope deferred(isolate);
   DummyVisitor visitor;
   isolate->handle_scope_implementer()->Iterate(&visitor);
   deferred.Detach();
