The getter `SharedType.nullabilitySuffix` is replaced by
`SharedType.isQuestionType`, which returns a boolean.
The method `TypeAnalyzerOperations.withNullabilitySuffixInternal` is
replaced by `SharedType.setNullabilitySuffix`, which accepts a
boolean.
Support for `*` types has been removed from `mini_types.dart`.
A few test cases in `flow_analysis_test.dart` previously used `*`
types as a way of exercising corner cases involving types that were
mutual subtypes of each other. These tests have been changed to take
advantage of the fact that `dynamic` and `Object?` are mutual
subtypes.
