'ConstructorDescriptor#getConstructedClass()' should be used to obtain a descriptor for constructed class

KT-15109 Subclass from a type alias with named parameter in constructor will produce compiler exception
KT-15192 Compiler crashes on certain companion objects: "Error generating constructors of class Companion with kind IMPLEMENTATION"
