    [turbofan] relative_id of splinters and their children. · 96c0e6f9
    mtrofin authored
    A LiveRange is identified by 2 integers: the vreg() of its TopLevel,
    which is the virtual register (operand) ID; and a relative_id(), which has
    no meaning in the program, but is valuable in debugging or tracing
    scenarios.
    
    This change ensures that relative_id is unique even in cases of splinter
    ranges and their children.
