Johnni Winther eaedc90684 [_fe_analyzer_shared] Improve handling of map patterns
This adds improved support for map patterns. A new [Restriction]
class replaces the [TypeBasedStaticType.identity] properties and
allows not only for unique values as subtypes but also subsets of
values as subtypes. For map pattern the subsets are defined by
a [MapTypeIdentity] based on the type arguments of the map pattern,
its constant key values and whether it has a rest pattern.

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.
