uses it to add tests for scopes in extensions, extension types and

on the scope on instance members in extensions and extension types for
the synthetic #this variable.

corresponding DDC test. The CFE test uses the DartScopeBuilder2
which is currently in development to replace the DartScopeBuilder.
