Changed PostTyperTransformer scheme

1) We now always generate companion objects for classes. This is done in
   mini-phase "companions", which also assures that companion-modules appear
   after companion-classes.

2) PostTyperTransformers is gone; the part which normalizes trees has been
   rolled into TreeTransform and the part which reordered companion classes
   and modules is now in Companions.

Note: Some tests were deisabled; should be re-enabled by Dmitry where needed.
