simpleperf: Fix BR_INST_RETIRED.NEAR_TAKEN for Intel Atom CPUs Intel Atom CPUs use a different umask for BR_INST_RETIRED.NEAR_TAKEN, as shown in https://github.com/intel/perfmon/blob/main/scripts/perf/alderlake/pipeline.json#L303. This patch detects Intel Atom CPUs and changes config when opening perf event files on those CPUs. Bug: 345410289 Test: run simpleperf manually Test: run simpleperf_unit_test Change-Id: Ic17bf663fa77c3fbd2df446ba941755a1cd51958
