    perf tools: Add inverted call graph report support. · d797fdc5
    Sam Liao 提交于
    Add "caller/callee" option to support inverted butterfly report,
    in the inverted report (with caller option), the call graph start
    from the callee's ancestor. Users can use such view to catch system's
    performance bottleneck from a sysprof like view. Using this option
    with specified sort order like pid gives us high level view of call
    graph statistics.
    
    Also add "-G" alias for inverted call graph.
