Properly detect Kotlin built-ins:

Built-in classes like jet.Int and jet.Iterable are loaded from source files by KotlinBuiltIns class. It makes no sense to create JetLightClass instances for such classes, moreover, it causes runtime failures. Now we check the location a file was loaded from before creating a light class, and skip if it is a built-in. We also assert this in teh actual generation of light class bodies, and print out OS information if something fails, because our detection strategy may depend on OS-specific behavior.
