perf script: Add --inline option for debugging
The --inline option is to show inlined functions in callchains.
For example:
$ perf script
a.out 5644 11611.467597: 309961 cycles:u:
790 main (/home/namhyung/tmp/perf/a.out)
20511 __libc_start_main (/usr/lib/libc-2.25.so)
8ba _start (/home/namhyung/tmp/perf/a.out)
...
$ perf script --inline
a.out 5644 11611.467597: 309961 cycles:u:
790 main (/home/namhyung/tmp/perf/a.out)
std::__detail::_Adaptor<std::linear_congruential_engine<unsigned long, 16807ul, 0ul, 2147483647ul>, double>::operator()
std::uniform_real_distribution<double>::operator()<std::linear_congruential_engine<unsigned long, 16807ul, 0ul, 2147483647ul> >
std::uniform_real_distribution<double>::operator()<std::linear_congruential_engine<unsigned long, 16807ul, 0ul, 2147483647ul> >
main
20511 __libc_start_main (/usr/lib/libc-2.25.so)
8ba _start (/home/namhyung/tmp/perf/a.out)
