* @source: source parsed from a disassembler like objdump -dS
* @cyc_hist: Average cycles per basic block

* lines is allocated, percentages calculated and all sorted by percentage
* when the annotation is about to be presented, so the percentages are for
* one of the entries in the histogram array, i.e. for the event/counter being
