Subject: [PATCH] Write kotlin metadata on class-files for coroutine state
 machines

Otherwise it breaks JPS assumptions, that leads to exceptions like:
Error:Kotlin: [Internal Error] java.lang.AssertionError: Couldn't load KotlinClass from /Users/jetbrains/IdeaProjects/KotlinPlaygroundBeta11/out/production/KotlinPlaygroundBeta11/Counter$both$1.class; it may happen because class doesn't have valid Kotlin annotations
    at org.jetbrains.kotlin.build.GeneratedJvmClass.<init>(generatedFiles.kt:36)
    at org.jetbrains.kotlin.jps.build.KotlinBuilder.getGeneratedFiles(KotlinBuilder.kt:469)
    at org.jetbrains.kotlin.jps.build.KotlinBuilder.doBuild(KotlinBuilder.kt:241)
    at org.jetbrains.kotlin.jps.build.KotlinBuilder.build(KotlinBuilder.kt:140)
...
