This works in many cases, however, it is incomplete since there
are cases where classes are extracted to top-level and therefore
reparented. Therefore, we lose the information about the function
class are nested inside.
Codegen generates static backing fields for object properties.
They are initialized in class constructor but some of them are final static
and such access is prohibited in specification but it's allowed in
java bytecode <= 1.8. Such access in 1.9 bytecode cause
"IllegalAccessError: Update to static final field Object.INSTANCE
attempted from a different method (<init>) than the initializer method <clinit>"
Added additional hidden field in interface companion to pass out
companion instance from <clinit>.
#KT-15894 Fixed
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
