[PATCH v4 04/14] perf stat: Extend STD output linter to test core aggregation checks

[Ian Rogers <irogers@google.com>]

This patch extends tools/perf/tests/shell/stat+std_output.sh to run all
standard CPU and thread aggregation checks under the --new print flag:

  - check_system_wide
  - check_system_wide_no_aggr
  - check_interval
  - check_per_thread
  - check_per_node
  - check_per_core
  - check_per_socket
  - check_per_die

This guarantees that standard console outputs produced by the decoupled
printing engine are verified across all core CPU-aggregation modes.
