    Default RuntimeRep variables unless -fprint-explicit-runtime-reps
    
    Summary:
    Addresses #11549 by defaulting `RuntimeRep` variables to `PtrRepLifted`
    and adding a new compiler flag `-fprint-explicit-runtime-reps` to
    disable this behavior.
    
    This is just a guess at the right way to go about this. If it's
    wrong-beyond-any-hope just say so.
    
    Test Plan: Working on a testcase
