Currently the srcline sort key compares ip rather than srcline info. I guess this was due to a performance reason to run external addr2line utility. Now we have implemented the functionality inside, use the srcline info when comparing hist entries. Also constantly print "??:0" string for unknown srcline rather than printing ip.
