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);
