Rationale: Found by DartFuzz, AOT did not always properly implement the == test on null. Associated regression test is heavily stripped down test. https://github.com/dart-lang/sdk/issues/35325 https://github.com/dart-lang/sdk/issues/32166 Change-Id: If01d944295a089b438aabf7092987706e442ba26 Reviewed-on: https://dart-review.googlesource.com/c/86300 Reviewed-by: Alexander Markov <alexmarkov@google.com> Commit-Queue: Aart Bik <ajcbik@google.com>
