Redundant diagnostic suppression

Reports usages of @Suppress annotations that can be safely removed because the compiler diagnostic they affect is no longer applicable in this context.

Example:

  fun doSmth(@Suppress("UNUSED_PARAMETER") used: Int) {
    println(used)
  }

After the quick-fix is applied:

  fun doSmth(used: Int) {
    println(used)
  }
