perf test: Add checking for perf stat CSV output.
Counts expected fields for various commands. No testing added for
summary mode since it is broken.
An example of the summary output is:
summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
,,,,,1.37,stalled cycles per insn
This should be:
summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
summary,,,,,,1.37,stalled cycles per insn
The output has 7 fields when it should have 8. Additionally, the newline
spacing is wrong, so it was excluded from testing until a fix is made.
Committer testing:
$ perf test "perf stat CSV output"
88: perf stat CSV output linter : Ok
$
$ perf test -v "perf stat CSV output"
Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
88: perf stat CSV output linter :

I did a s/parnoia/paranoid/g on the [Skip] lines.
