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) ...
