and pfmon_itanium2.c.

* added --smpl-print-counts option. By default counts are not
printed when sampling unless this option is specified.
* added warning in compact sampling output mode header when
randomization is not supported by kernel. We keep the same
number of columns but the value is zero instead of the initial
value of first overflowed PMD.
