Chloe Stefantsova a46de1c30c [cfe] Add implicit null-check on throw 
Throwing `null` is not supported in sound null safety. This change
inserts an implicit `as Object` cast that result in a TypeError, rather
than a NullThrownError, in sound mode.

Closes https://github.com/dart-lang/sdk/issues/49198

Front end for Dart

This package provides a low-level API for use by compiler back ends that wish to implement the Dart language. It is intended for eventual use by dev_compiler, dart2js, and the Dart VM. In addition, it will share implementation details with the analyzer package--this will be accomplished by having the analyzer package import (and re-export) parts of this package's private implementation.

End-users should use the dart analyze command-line tool to analyze their Dart code.

Integrators that want to write tools that analyze Dart code should use the analyzer package.

Note: A previous version of this package was published on pub.dev. It has now been marked DISCONTINUED as it is not intended for direct consumption, as per the notes above.
