Proposed as expressions with needlessly nullable type

[johnniwinther]

When migrating

Class get enclosingClass => parent is Class ? parent : null;

the proposed edit was added an as Class?:

Class? get enclosingClass => parent is Class ? parent as Class? : null;
                                                      ^^^^^^^^^

and not the more precise as Class:

Class? get enclosingClass => parent is Class ? parent as Class : null;
                                                      ^^^^^^^^

This is another issue with the migration tool being too cautious because of the lack of field promotion. Should be addressed by #40566.

As of 1c7fe71, the null safety migration tool has been removed from active development and retired. No further work on the tool is planned.
