C2 SuperWord: refactor/improve TraceSuperWord, replace VectorizeDebugOption with TraceAutoVectorization

      I got approval to remove VectorizeDebugOption: JDK-8320668

      I want a more general flag for AutoVectorization, that can trace different components of AutoVectorization.
      It should be a CompileCommand, so that it can select which methods it traces for.

      TraceSuperWord should still look similar, and select a subset of the TraceAutoVectorization components (those for SuperWord), but still apply to all classes/methods.

      With more refactoring later in JDK-8315361, this flag should become more usable and interpretable.
