* kotlinx.atomicfu compiler plugin for JS_IR Support transformations of atomic operations introduced by the kotlinx.atomicfu library for the JS_IR backend. Compiler plugin is applied externally by the kotlinx.atomicfu gradle plugin. * Apply compiler plugin for JS platform only * New plugin test structure * testGroupOutputDirPrefix changed
