perf ui/stdio: Implement hierarchy output mode
The hierarchy output mode is to group entries for each level so that
user can see higher level picture more easily. It also helps to find
out which component is most costly. The output will look like below:
15.11% swapper
14.97% [kernel.vmlinux]
0.09% [libahci]
0.05% [iwlwifi]
10.29% irq/33-iwlwifi
6.45% [kernel.vmlinux]
1.41% [mac80211]
1.15% [iwldvm]
1.14% [iwlwifi]
0.14% [cfg80211]
4.81% firefox
3.92% libxul.so
0.34% [kernel.vmlinux]
