PrintInlining as compiler directive doesn't print virtual calls

If we set PrintInlining for a specific method only with the help of a compiler directive (e.g. -XX:CompileCommand="option,Inlining::foo,PrintInlining") it won't print virtuall calls which can't be inlined. These calls are printed if we use the global -XX:+PrintInlining option.

The fix is trivial:
