I hit a bug when running test suite without forking each test (-F
option):
$ perf test -Fv
...
34: Test thread map :
--- start ---
FAILED tests/thread-map.c:24 wrong comm
---- end ----
Test thread map: FAILED!
The reason was the process name wasn't 'perf' as expected by the test,
because other tests set the name as well.
Setting it explicitly now.

Introduce the perf_event__synthesize_thread_map2 function to synthesize
struct thread_map.
The perf_event__synthesize_thread_map name is already taken for
synthesizing the complete threads data (comm/mmap/fork).

Some tests have sub-tests we want to run, so allow passing this.
Wang tried to avoid having to touch all tests, but then, having the
test.func in an anonymous union makes the build fail on older compilers,
like the one in RHEL6, where:
test a = {
.func = foo,
};
fails.
To fix it leave the func pointer in the main structure and pass the subtest
index to all tests, end result function is the same, but we have just one
function pointer, not two, with and without the subtest index as an argument.
