When we detect that a temporary variable is being reused with a different type, we change the type of the temp to dynamic. This allows us to retain types for any non-reused temps. For any dynamic temps we still have type information available for use sites, which we can pass on via unsafeCast. One drawback of this approach is that we don't know ahead of time which temps are reused, and get turned into dynamic, so we have to unsafeCast all uses. This change is similar to what was done in: https://dart-review.googlesource.com/c/sdk/+/138500 TEST=Adds tests/language/vm/regress_flutter_85311_test.dart, updates relevant expect files.

Dart Kernel
Dart Kernel is a small high-level language derived from Dart. It is designed for use as an intermediate format for whole-program analysis and transformations, and to be consumed by codegen and execution backends.
The kernel language has an in-memory representation in Dart and can be serialized as binary or text.
Both the kernel language and its implementations are unstable and are under development.
This package contains the Dart part of the implementation and contains:
- A transformable IR for the kernel language
- Serialization of kernel code
Note: The APIs in this package are in an early state; developers should be careful about depending on this package. In particular, there is no semver contract for release versions of this package. Please depend directly on individual versions.
See ast.dart for the in-memory IR, or binary.md for a description of the binary format. For now, the textual format is very ad-hoc and cannot be parsed back in.
