Kernel mixin transformation desugars mixin applications into normal classes. Mixed-in type is pulled into interfaces list. However, dart:mirrors needs to know the original mixed-in type of a mixin application. This change solves this problem by propagating a 'isTransformedMixinApplication' attribute of a class through kernel AST, kernel binary and VM objects into dart:mirrors implementation.
