pyos e49410e07b JVM_IR: optimize delegation by property references
E.g. a statement like

    var x by ::y

is semantically equivalent to

    var x
      get() = y
      set(value) { y = value }

and thus does not need a full property reference object, or even a field
if the receiver is not bound.
