[vm/compiler] avoid literal null is non-nullable Rationale: Having a literal null checked by CheckNull with a subsequent Redefinition resulted in some strange unboxing that crashed AOT (fix courtesy Slava!). Note that we still have some ambiguity around adding/removing environments from instructions that may deoptimize, but this change fixes all prior related DartFuzz failures. https://github.com/dart-lang/sdk/issues/35335 Change-Id: Ifb50d8cddf93e57758b2bbb83ad397ea281e9307 Reviewed-on: https://dart-review.googlesource.com/c/87280 Reviewed-by: Vyacheslav Egorov <email@example.com> Commit-Queue: Aart Bik <firstname.lastname@example.org>
