Changes from v9:
* Move PMCCNTR related configuration from pmu_init() to sub-tests
* Change the name of loop test function to precise_cycles_loop()
* Print out error detail for each test case in check_cpi()
* Fix cpi convertion from argv
* Change the loop calculation in measure_instrs() after cpi is fixed

Note:
1) Current KVM code has bugs in handling PMCCFILTR write. A fix (see
below) is required for this unit testing code to work correctly under
KVM mode.
