Add socket as a separate member so that it doesn't have to be packed
into the int value.
When the socket ID was larger than 8 bits the output appeared corrupted
or incomplete.
For example, here on ThunderX2 'perf stat' reports a socket of -1 and an
invalid die number:
./perf stat -a --per-die
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255 128 687.99 msec cpu-clock # 57.240 CPUs utilized
...
S36-D0 128 842.34 msec cpu-clock # 70.081 CPUs utilized
...
And with --per-core there is an entry with an invalid core ID:
./perf stat record -a --per-core
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255-C65535 128 671.04 msec cpu-clock # 54.112 CPUs utilized
...
S36-D0-C0 4 28.27 msec cpu-clock # 2.279 CPUs utilized
...
This fixes the "Session topology" self test on ThunderX2.
After this fix the output contains the correct socket and die IDs and no
longer prints a warning about the size of the socket ID:
./perf stat --per-die -a

Commit e1c92a7fbb ("perf tests: Add another metric parsing test") add
another test for metric parsing. The test goes through all metrics
compiled for arch within pmu events and try to parse them.
Right now this test is failing in powerpc machine.
Result in power9 platform:
[command]# ./perf test 10
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Skip (some metrics failed)
10.4: Parsing of PMU event table metrics with fake PMUs : FAILED!
Issue is we are passing different runtime parameter value in
"expr__find_other" and "expr__parse" function which is called from
function `metric_parse_fake`. And because of this parsing of hv-24x7
metrics is failing.
[command]# ./perf test 10 -vv

Recently there was an undetected breakage for std arch event support.
Add support in "PMU events" testcase to detect such breakages.
For this, the "test" arch needs has support added to process std arch
events. And a test event is added for the test, ifself.
Also add a few code comments to help understand the code a bit better.

x86 arch provides the testing for conversion between tsc and perf time,
the testing is located in x86 arch folder. Move this testing out from
x86 arch folder and place it into the common testing folder, so allows
to execute tsc testing on other architectures (e.g. Arm64).
This patch removes the inclusion of "arch-tests.h" from the testing
code, this can avoid building failure if any arch has no this header
file.

Peter suggested that using the exclusive mode in perf could avoid some
problems with bad scheduling of groups. Exclusive is implemented in the
kernel, but wasn't exposed by the perf tool, so hard to use without
custom low level API users.
Add support for marking groups or events with :e for exclusive in the
perf tool. The implementation is basically the same as the existing
pinned attribute.
