Paul Berry 96a346fc5e Front end: move anonymous mixin sealed/final inference to checkSupertypes phase. 
Previously this step happened during `buildOutlineNodes`, but since
`buildOutlineNodes` happens in source order, this means that anonymous
mixins would only get their sealed and final attributes properly
inferred if they appeared *after* their immediate supertypes in source
order.  By moving this step to `checkSupertypes`, we ensure that the
computation is correct regardless of source order, because
`checkSupertypes` happens in class hierarchy order.

Fixes #52048.

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.
