perf/x86/intel: Add Intel Skylake PMU support
Add perf core PMU support for future Intel Skylake CPU cores. The code is based on Haswell/Broadwell. There is a new cache event list, based on the updated Haswell event list. Skylake has removed most counter constraints on basic events, so the basic constraints table now only has a single entry (plus the fixed counters). TSX support and various other setups are all shared with Haswell. Skylake has 32 LBR entries. Add a new LBR init function to set this up. The filters are all the same as Haswell. It also has a new LBR format with a separate LBR_INFO_* MSR, but that has been already added earlier.
