Description
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.
