perf script: Enable printing of interrupted machine state

To capture the interrupted machine state: $ perf record -I .... to display iregs, use the -F option: $ perf script -F ip,iregs 40afc2 AX:0x6c5770 BX:0x1e CX:0x5f4d80a DX:0x101010101010101 SI:0x1 Signed-off-by: NStephane Eranian <eranian@google.com> Tested-by: NArnaldo Carvalho de Melo <acme@redhat.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Kan Liang <kan.liang@intel.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1441039273-16260-2-git-send-email-eranian@google.comSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>
