* JVM incorrectly mapped T<KClass<...>> to T<Class<...>> because the
annotation-ness of the type mapping mode was inherited one level
down into a generic signature independent of T
* JVM_IR was even worse as it did not use VALUE_FOR_ANNOTATION at all,
mapping T<T<KClass<...>> to T<T<Class<...>> as well.
The correct behavior is to map KClass to Class only at top level or as
an argument of Array.
