IC of sealed classes

Supported case then children of sealed classes could be declared
anywhere in a module. If list of classes implementing sealing class
changes the sealed class and all its inheritors should be recompiled
(now sealed class should be compiled together with children in order
to calculate all possible inheritors at compile time) and and
invalidated (as they could have when operators).
