Otherwise a local class in a field initializer or anonymous init block is copied into each constructor of the containing class (because InitializersLowering calls deepCopy). Since the code structure no longer resembles the original source code here, record a custom EnclosingMethod mapping before moving such classes, and use it in codegen.
