407eb43ae8 libperf: Add arm64 support to perf_mmap__read_self() 
Add the arm64 variants for read_perf_counter() and read_timestamp().
Unfortunately the counter number is encoded into the instruction, so the
code is a bit verbose to enumerate all possible counters.

3ff6d64e68 libperf tests: Fix test_stat_cpu 
The `cpu` argument of perf_evsel__read() must specify the cpu index.

perf_cpu_map__for_each_cpu() is for iterating the cpu number (not index)
and is thus not appropriate for use with perf_evsel__read().

So, if there is an offline CPU, the cpu number specified in the argument
may point out of range because the cpu number and the cpu index are
different.

Fix test_stat_cpu().

Testing it:

maintenance is easier.

Adding tests under libperf build system, so we define all the flags just

Adding make-tests tule to just compile tests without running them.

47d01e7b99 libperf: Add support for user space counter access 
x86 and arm64 can both support direct access of event counters in
userspace. The access sequence is less than trivial and currently exists
in perf test code (tools/perf/arch/x86/tests/rdpmc.c) with copies in
projects such as PAPI and libpfm4.

In order to support userspace access, an event must be mmapped first
with perf_evsel__mmap(). Then subsequent calls to perf_evsel__read()
will use the fast path (assuming the arch supports it).

Committer notes:

Added a '__maybe_unused' attribute to the read_perf_counter() argument
to fix the build on arches other than x86_64 and arm.

Committer testing:

  Building and running the libperf tests in verbose mode (V=1) now shows
  those "loop = N, count = N" extra lines, testing user space counter
  access.

d3003d9e68 libperf tests: Add support for verbose printing 
Add __T_VERBOSE() so tests can add verbose output. The verbose output is
enabled with the '-v' command line option. Running 'make tests V=1' will
enable the '-v' option when running the tests.

It'll be used in the next patch, for a user space counter access test.

bba2ea17ef libperf tests: If a test fails return non-zero 
If a test fails return -1 rather than 0. This is consistent with the
return value in test-cpumap.c

be82fddca8 libperf tests: Avoid uninitialized variable warning 
The variable 'bf' is read (for a write call) without being initialized
triggering a memory sanitizer warning. Use 'bf' in the read and switch
the write to reading from a string.
