    Jiri Olsa authored
    Adding new test that process metrics code and checks the expected
    results. Starting with easy ipc metric.
    
    Committer testing:
    
      # perf test "Parse and process metrics"
      67: Parse and process metrics                             : Ok
      #
      # perf test -v "Parse and process metrics"
      67: Parse and process metrics                             :
      --- start ---
      test child forked, pid 103402
      metric expr inst_retired.any / cpu_clk_unhalted.thread for IPC
      found event inst_retired.any
      found event cpu_clk_unhalted.thread
      adding {inst_retired.any,cpu_clk_unhalted.thread}:W
      test child finished with 0
      ---- end ----
      Parse and process metrics: Ok
      #
    
    Had to fix it to initialize that 'struct value' array sentinel with a
    named initializer to fix the build with some versions of clang:
    
      tests/parse-metric.c:135:7: error: missing field 'val' initializer [-Werror,-Wmissing-field-initializers]
                    { 0 },
