Dmitry Petrov 7c3d079eeb Fix issues with enum entry self-reference ...

Given a singleton class 'S' with possibly uninitialized static instance
(enum entry, interface companion object).
Such singleton can be referenced by name, or as an explicit or implicit
'this'.
For a given singleton class 'S' we
either use 'this@S' from context (local or captured),
or 'S' as a static instance.

Local or captured 'this@S' should be used if:
  - we are in the constructor for 'S',
    and corresponding instance is initialized
        by super or delegating constructor call;
  - we are in any other member of 'S' or any of its inner classes.

Otherwise, a static instance should be used.
