---------------8<---------------
interesting cases here are '==' for primitive and objects and any < =< > >= and separatelly !=

Kotlin-native backend
Build
Download dependencies:
gradle :dependencies:update
To run native translator just use:
gradle :backend.native:run
And it will run simple example (currently prints out IR of test file). For more tests, use:
gradle :backend.native:tests:run
