Updated to ignore metadata while simplifying with InstructionSimplify. I've updated the description with details.
It adds a very crude way to disable the use of metadata. Not sure if we want a more fine grained approach. The cosmetics of the UseMetadata handling can be improved slightly, happy to do that if the overall approach is sensible.
