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.

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.
