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.

FE/analyzer shared code
This package contains logic that is shared between the front_end and analyzer packages. It is intended solely to facilitate development of the Dart SDK, and is not intended for use by end users. In particular, this package has no public API, so no guarantee is made of compatibility between one version of the package and the next.
End users should consider using the analyzer package to analyze Dart source code.
