From: Jiri Olsa <jolsa@kernel.org>

Michael reported 'perf mem -t store record' being broken.  The reason is
latest rework of this area:

  commit acbe613e0c03 ("perf tools: Add monitored events array")

We don't mark perf_mem_events store record when -t store option is
specified.

Committer notes:

Before:

  # perf mem -t store record usleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ]
  # perf evlist
  cycles:ppp
  #

After:

  # perf mem -t store record usleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ]
  # perf evlist
  cpu/mem-stores/P
  #
