Arnaldo Carvalho de Melo 409a8be615 perf tools: Add sort by src line/number
Using addr2line for now, requires debuginfo, needs more work to support
detached debuginfo, aka foo-debuginfo packages.

Example:

	[root@sandy ~]# perf record -a sleep 3
	[ perf record: Woken up 1 times to write data ]
	[ perf record: Captured and wrote 0.555 MB perf.data (~24236 samples) ]
	[root@sandy ~]# perf report -s dso,srcline 2>&1 | grep -v ^# | head -5
	    22.41%  [kernel.kallsyms]  /home/git/linux/drivers/idle/intel_idle.c:280
	     4.79%  [kernel.kallsyms]  /home/git/linux/drivers/cpuidle/cpuidle.c:148
	     4.78%  [kernel.kallsyms]  /home/git/linux/arch/x86/include/asm/atomic64_64.h:121
	     4.49%  [kernel.kallsyms]  /home/git/linux/kernel/sched/core.c:1690
	     4.30%  [kernel.kallsyms]  /home/git/linux/include/linux/seqlock.h:90
	[root@sandy ~]#

[root@sandy ~]# perf top -U -s dso,symbol,srcline
