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. https://lists.cs.columbia.edu/pipermail/kvmarm/2016-November/022134.html.
