Subject: [PATCH 15/15] perf mem: Add Intel DATALA memory events

Adding Intel DATALA memory events into
perf mem record command:

  $ perf mem record -e list
  ldlat-loads      : available
  ldlat-stores     : available
  stlb-miss-loads
  stlb-miss-stores
  lock-loads
  split-loads
  split-stores
  all-loads
  all-stores
  l1-hit
  l2-hit
  l3-hit
  l1-miss
  l2-miss
  l3-miss
  lfb
  snp-miss
  snp-hit
  snp-hitm
  snp-none
  local-dram

All events from above lists are compiled in, but only
those with [ok] are supported by kernel/HW. You need
previous DATALA patch to support all of them.
