perf tools: Add 'addr' sort key

Sometimes users want to see actual (virtual) address of sampled instructions.
Add a new 'addr' sort key to display the raw addresses.

  $ perf record -o- true | perf report -i- -s addr
  # To display the perf.data header info, please use --header/--header-only options.
  #
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.000 MB - ]
  #
  # Total Lost Samples: 0
  #
  # Samples: 12  of event 'cycles:u'
  # Event count (approx.): 252512
  #
  # Overhead  Address
  # ........  ..................
  #
      42.96%  0x7f96f08443d7
      29.55%  0x7f96f0859b50
      14.76%  0x7f96f0852e02
       8.30%  0x7f96f0855028
       4.43%  0xffffffff8de01087

Note that it just compares and displays the sample ip.  Each process can
have a different memory layout and the ip will be different even if they run
the same binary.  So this sort key is mostly meaningful for per-process
profile data.
