The following fixes landed separately:

* Auto-detection of null-safety mode from dill file in gen_snapshot is
implemented in https://dart-review.googlesource.com/c/sdk/+/148152.
Original change's description:
> [vm/nnbd] Auto-detect null-safety from entry point in kernel compilers
>
> If --null-safety flag is not specified, tools should infer null safety
> mode from a legacy status of an entry point script.
> This change adds such auto-detection to kernel compilers (front-end
> server and gen_kernel).
