BTS records branch_from_addr and branch_to_addr in IP and ADDR field in perf_sample.
This patch enables to print them in following format,
<from_addr> <from_symbol> (<from_dso>) => <to_addr> <to_symbol> (<to_dso>)
Sample:
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e016b0 _start (/lib64/ld-2.14.so)
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e016b0 _start (/lib64/ld-2.14.so)
3f03e016b3 _start (/lib64/ld-2.14.so) => 3f03e04b80 _dl_start (/lib64/ld-2.14.so)
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e04b80 _dl_start (/lib64/ld-2.14.so)
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e04ba6 _dl_start (/lib64/ld-2.14.so)
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e04bad _dl_start (/lib64/ld-2.14.so)
3f03e04bfb _dl_start (/lib64/ld-2.14.so) => 3f03e04c1d _dl_start (/lib64/ld-2.14.so)
