    of the generated code.  These can be used by the profiler to
    categorize the ticks that occur within generated code and thereby show
    more detailed information about where time is spent in generated code.
    For instance, this is what the profiler displayed for a simple regexp
    benchmark with irregexp-native before:
    
    [JavaScript]:
       total  nonlib   name
       87.2%   87.2%   RegExp: (?:\w*\W+)*
    
    This is what we can display now:
    
    [JavaScript]:
       total  nonlib   name
       87.2%   87.2%   RegExp: (?:\w*\W+)*
                       -  53.0%  56.7% BranchOrBacktrack
