    Merge #1082
    
    1082: Add base for privacy visitor r=CohenArthur a=CohenArthur
    
    This PR is extremely early and implements some building blocks for privacy visitors. I'd like to get some feedback on the architecture and, if satisfactory, merge this first "visitor" which only takes care of visiting HIR struct definitions, to make reviewing easier. We could also merge it to a different branch for now, in order to not add an incomplete pass to the compiler.
    
    Thanks!
