perf script: Enable printing of interrupted machine state
This patch adds the output of the interrupted machine state (iregs) to
perf script. It presents them as NAME:VALUE so this is easy to parse
during post processing.
To capture the interrupted machine state:
$ perf record -I ....
to display iregs, use the -F option:
$ perf script -F ip,iregs
