Alexander Shishkin ccbebba4c6 perf/x86/intel/pt: Bypass PT vs. LBR exclusivity if the core supports it
Not all cores prevent using Intel PT and LBRs simultaneously, although
most of them still do as of today. This patch adds an opt-in flag for
such cores to disable mutual exclusivity between PT and LBR; also flip
it on for Goldmont.
