perf_counter tools: Resolve symbols in callchains
This patch resolves the names, when possible, of each ip
present in the callchains while using the -c option with perf
report.
Example:
5.40% [k] __d_lookup
5.37%
perf_callchain
perf_counter_overflow
intel_pmu_handle_irq
perf_counter_nmi_handler
notifier_call_chain
atomic_notifier_call_chain
notify_die
do_nmi
nmi
do_lookup
__link_path_walk
path_walk
do_path_lookup
user_path_at
sys_faccessat
sys_access
system_call_fastpath
0x7fb609846f77
0.01%
