Paul Berry 75573ad6f9 Fix engine in preparation for implementing https://github.com/dart-lang/language/issues/1274 (flutter/engine#23131) ...

When https://github.com/dart-lang/language/issues/1274 (Infer
non-nullability from local boolean variables) is implemented, flow
analysis will detect that code like this no longer needs to perform a
null check:

    final bool hasIdentityTransform =
        transform == null || isIdentityFloat32ListTransform(transform);
    ...
    if (!hasIdentityTransform) {
      ... transform! ... // Null check unnecessary
    }

To avoid a build failure due to the unnecessary null check, we need to
temporarily write it in a way that we can ignore it.  Once the feature
is complete and rolled into flutter, I'll remove the null check
entirely.
