Subject: [PATCH v2 06/14] perf script: mark inlined frames and do not print DSO for them

Instead of showing the (repeated) DSO name of the non-inlined
frame, we now show the "(inlined)" suffix instead.

Before:
                   214f7 __hypot_finite (/usr/lib/libm-2.25.so)
                    ace3 hypot (/usr/lib/libm-2.25.so)
                     a4a std::__complex_abs (/home/milian/projects/src/perf-tests/inlining)
                     a4a std::abs<double> (/home/milian/projects/src/perf-tests/inlining)
                     a4a std::_Norm_helper<true>::_S_do_it<double> (/home/milian/projects/src/perf-tests/inlining)
                     a4a std::norm<double> (/home/milian/projects/src/perf-tests/inlining)
                     a4a main (/home/milian/projects/src/perf-tests/inlining)
                   20510 __libc_start_main (/usr/lib/libc-2.25.so)
                     bd9 _start (/home/milian/projects/src/perf-tests/inlining)

After:
                   214f7 __hypot_finite (/usr/lib/libm-2.25.so)
                    ace3 hypot (/usr/lib/libm-2.25.so)
                     a4a std::__complex_abs (inlined)
                     a4a std::abs<double> (inlined)
                     a4a std::_Norm_helper<true>::_S_do_it<double> (inlined)
                     a4a std::norm<double> (inlined)
                     a4a main (/home/milian/projects/src/perf-tests/inlining)
                   20510 __libc_start_main (/usr/lib/libc-2.25.so)
                     bd9 _start (/home/milian/projects/src/perf-tests/inlining)
