To pass more info to the saved_value in the runtime_stat, add a new
struct runtime_stat_data. Currently it only has 'ctx' field but later
patch will add more.

* [PATCH v2 2/2] perf stat: Take cgroups into account for shadow stats

As of now it doesn't consider cgroups when collecting shadow stats and
metrics so counter values from different cgroups will be saved in a
same slot. This resulted in an incorrect numbers when those cgroups
have different workloads.
For example, let's look at the below - the cgroup A and C runs same
workload which burns a cpu while cgroup B runs a light workload.
$ perf stat -a -e cycles,instructions --for-each-cgroup A,B,C sleep 1
Performance counter stats for 'system wide':
3,958,116,522 cycles A
6,722,650,929 instructions A # 2.53 insn per cycle
1,132,741 cycles B
571,743 instructions B # 0.00 insn per cycle
4,007,799,935 cycles C
6,793,181,523 instructions C # 2.56 insn per cycle
1.001050869 seconds time elapsed
When I run perf stat with single workload, it usually shows IPC around 1.7.
We can verify it (6,722,650,929.0 / 3,958,116,522 = 1.698) for cgroup A.
But in this case, since cgroups are ignored, cycles are averaged so it
used the lower value for IPC calculation and resulted in around 2.5.
avg cycle: (3958116522 + 1132741 + 4007799935) / 3 = 2655683066
IPC (A) : 6722650929 / 2655683066 = 2.531
IPC (B) : 571743 / 2655683066 = 0.0002
IPC (C) : 6793181523 / 2655683066 = 2.557
We can simply compare cgroup pointers in the evsel and it'll be NULL
when cgroups are not specified. With this patch, I can see correct
numbers like below:
$ perf stat -a -e cycles,instructions --for-each-cgroup A,B,C sleep 1
Performance counter stats for 'system wide':
4,171,051,687 cycles A
7,219,793,922 instructions A # 1.73 insn per cycle
1,051,189 cycles B
583,102 instructions B # 0.55 insn per cycle
4,171,124,710 cycles C
7,192,944,580 instructions C # 1.72 insn per cycle
1.007909814 seconds time elapsed

I think this should go to separate patch and be explained,
the change is advertised as adding struct for arguments

Actually it was already there and I found it during this work.
Basically it passes ctx for lookup but it uses 0 for time.
