perf tools: Add x86 RDPMC, RDTSC test
Implement a simple test for the self-monitoring data from the
perf mmap data area control page:
6: x86 rdpmc test:
0: 6053
1: 60053
2: 600059
3: 6000059
4: 60000075
5: 600000247
Ok
The counts are expected to increase monotonically - these
are recovered via RDPMC, without calling into the kernel.
It might be nice to add logic to automagically turn these numbers into OK/FAIL.
