Assert error for aliased constructors in annotations

[johnniwinther]

These annotations

class Class {
  const Class([a]);
  const Class.named({a, b});
}

class GenericClass<X, Y> {
  const GenericClass();
  const GenericClass.named({a, b});
}

typedef Alias = Class;
typedef ComplexAlias<X> = Class;
typedef GenericAlias<X, Y> = GenericClass<X, Y>;

@Class(Alias.named())
@Class(ComplexAlias())
@Class(ComplexAlias.named())
@Class(GenericAlias())
@Class(GenericAlias.named())
void type() {}

cause assertion errors like
'package:front_end/src/fasta/kernel/body_builder.dart': Failed assertion: line 1100 pos 11: 'delayedActionPerformers != null': Body builder has delayed actions that cannot be performed: [TypeAliasedConstructorInvocation(const Alias.named())]
