Since 1.4.0-dev-8774, we mangle functions returning inline class values,
including functions with return type 'kotlin.Result'. This causes
incompatibility when 1.4 compiler is used with 1.3 (or just some
pre-1.4.0-dev-8774) standard library.
Also, write "message from the future" on functions returning inline
class values indicating that they can be used since compiler version 1.4
(otherwise 1.3 compiler using 1.4 stdlib would fail to find some
@InlineOnly functions such as 'Result.success' and 'Result.failure').
We began to write version requirement on declarations with `Result` and
now (after bootstrap) we are getting error in this test because of that
version requirement.

Use the version requierement table of the outer DescriptorSerializer
instance when serializing metadata for a class. Pass parent serializer
to DescriptorSerializer.create to make sure the correct table is used.
Serialize nested classes before the outer class in JS and common code,
to make sure requirements are not lost. Also, split
