perf report: Add -F option to specify output fields
The -F/--fields option is to allow user setup output field in any
order. It can receive any sort keys and following (hpp) fields:
overhead, overhead_sys, overhead_us, sample and period
If guest profiling is enabled, overhead_guest_{sys,us} will be
available too.
The output fields also affect sort order unless you give -s/--sort
option. And any keys specified on -s option, will also be added to
the output field list automatically.
$ perf report -F sym,sample,overhead
...

Note that, the example output above is captured after applying next
patch which fixes sort/comparing behavior.
