Alexander Udalov 048a9b686e Generate separate anonymous class for each property reference
Each property reference obtained by the '::' operator now causes back-end to
generate an anonymous subclass of the corresponding KProperty class, with the
customized behavior. This fixes a number of issues:

- get/set/name of property references now works without kotlin-reflect.jar in
  the classpath
- get/set/name methods are now overridden with statically-generated property
  access instead of the default KPropertyImpl's behavior of using Java
  reflection, which should be a lot faster
- references to private/protected properties now work without the need to set
  'accessible' flag, because corresponding synthetic accessors are generated at
  compile-time near the target property
