Consider: ```class { val x : Int get() = 0 }``` On IrGenerationExtension while in same module ...

# compiler

Consider:

class {
  val x : Int
    get() = 0
}

On IrGenerationExtension while in same module IrProperty::backingField for x property is null,
but when referencing from another module it is not null (IrPluginContext::referenceClass and then find in class needed property) .
Why?
How to understand if property has backing field from another module?

Information about backing field is not stored in the metadata, so for declarations from dependencies it is set to some default (non-null)
