perf tools: Add support for sorting on the iaddr
Sorting on 'symbol' gives to broad a resolution as it can cover a range
of IP address. Use the iaddr instead to get proper sorting on IP
addresses. Need to use the 'mem_sort' feature of perf record.
New sort option is: symbol_iaddr, header label is 'Code Symbol'.
$ perf mem report --stdio -F +symbol_iaddr
