    Ensure that Literals in an Int# case are in range
    
    This is one way to fix #10246 and #13171. The chosen path involves
    adding the invariant that the argument of MachInt/MachWord etc. is
    always in the appropriate range, and that the smart constructors for
    them (mkMachInt etc.) wrap arguments that are outside the range in the
    expected way.
