Contributions summary:Evgeniy's commits primarily focus on refactoring and updating the Kotlin code base to use `JvmInline` value classes, replacing deprecated inline classes in tests. This involves modifying various test files, including those related to compiler and codegen tests, to align with the latest Kotlin features. The changes span multiple areas, impacting how inline classes are handled in different scenarios, like property delegation and interface implementation. Furthermore, the user updated tests to forbid synchronized by value classes and primitives.
