perf script: Print raw ip instead of binary offset for callchain
Before this, the raw ip is printed for non-callchain and dso offset for callchain. This inconsistent output for address may confuse people. And mostly what we expect is the raw ip. 'dso offset' is printed in callchain: $ perf script ... ls 1341034 2739463.008343: 2162417 cycles: ffffffff99d657a7 [unknown] ([unknown]) ffffffff99e00b67 [unknown] ([unknown]) 235d3 memset+0x53 (/usr/lib/x86_64-linux-gnu/ld-2.31.so) # dso offset a61b _dl_map_object+0x1bb (/usr/lib/x86_64-linux-gnu/ld-2.31.so) raw ip is printed for non-callchain: $ perf script -G ... ls 1341034 2739463.008876: 2053304 cycles: ffffffffc1596923 [unknown] ([unknown]) ls 1341034 2739463.009381: 1917049 cycles: 14def8e149e6 __strcoll_l+0xd96 (/usr/lib/x86_64-linux-gnu/libc-2.31.so) # raw ip Let's have consistent output for it. Later I'll add a new field 'dsoff' to print dso offset.
