As I mentioned in https://codereview.chromium.org/2726793003/, I believe main()
functions should all be outside of "lib/".  See that CL for details.

Yes. I've done that in CL 2722223006.

+  for (int i = 0; i < iterations; i++) {
+    if (i > 0) {
+      print("\n");
+    }
+    await compile(arguments);
+  }
+}
