[PATCH v3 0/5] perf test: Add a runs-per-test option

[Ian Rogers]

Add a runs-per-test option to perf test inorder to better diagnose
flakes. Each runs executes as if it were a different test, the tests
appear together in the output:

```
$ perf test -r 3 lbr -v
122: perf record LBR tests                                           : Ok
122: perf record LBR tests                                           : Ok
122: perf record LBR tests                                           : Ok
```

v3: Improve perf test documentation, including for the new option, and
    add some example output to the commit messages as requested by
    Namhyung.
v2: In the v1 patch Kan and I noted cleanup that would make the code
    cleaner and less indented:
    https://lore.kernel.org/lkml/20241109160219.49976-1-irogers@xxxxxxxxxx/
    Add patches doing some builtin-test.c cleanup and then add the
    runs-per-test flag.
