perf tools: Add +field argument support for --field option
Adding support to add field(s) to default field order via using the '+'
prefix, like for report:
$ perf report
Samples: 10 of event 'cycles', Event count (approx.): 4463799
Overhead Command Shared Object Symbol
32.40% ls [kernel.kallsyms] [k] filemap_fault
28.19% ls [kernel.kallsyms] [k] get_page_from_freelist
23.38% ls [kernel.kallsyms] [k] enqueue_entity
15.04% ls [kernel.kallsyms] [k] mmap_region
$ perf report -F +period,sample
Samples: 10 of event 'cycles', Event count (approx.): 4463799
Overhead Period Samples Command Shared Object Symbol
32.40% 1446493 1 ls [kernel.kallsyms] [k] filemap_fault
28.19% 1258486 1 ls [kernel.kallsyms] [k] get_page_from_freelist
23.38% 1043754 1 ls [kernel.kallsyms] [k] enqueue_entity
15.04% 671160 1 ls [kernel.kallsyms] [k] mmap_region
Works in general for commands using --field option.
