perf test: Add selftest to test IBS invocation via core pmu events
IBS pmu can be invoked via fixed set of core pmu events with 'precise_ip'
set to 1. Add a simple event open test for all these events.
Without kernel fix:
$ sudo ./perf test -vv 76
76: AMD IBS via core pmu :
--- start ---
test child forked, pid 6553
Using CPUID AuthenticAMD-25-1-1
type: 0x0, config: 0x0, fd: 3 - Pass
type: 0x0, config: 0x1, fd: -1 - Pass
type: 0x4, config: 0x76, fd: -1 - Fail
type: 0x4, config: 0xc1, fd: -1 - Fail
type: 0x4, config: 0x12, fd: -1 - Pass
test child finished with -1
---- end ----
