The test uses the newly added cap_usr_time_zero and time_zero of
perf_event_mmap_page. TSC from rdtsc is compared with the time
from 2 perf events. The test passes if the calculated times are
all in the correct order.

Adding automated test for breakpoint event signal handler checking if
it's executed properly.
The test is related to the proper handling of the RF EFLAGS bit on
x86_64, but it's generic for all archs.
First we check the signal handler is properly called and that the
following debug exception return to user space wouldn't trigger
recursive breakpoint.
This is related to x86_64 RF EFLAGS bit being managed in a wrong way.
Second we check that we can set breakpoint in signal handler, which is
not possible on x86_64 if the signal handler is executed with RF EFLAG
set.
This test is inpired by overflow tests done by Vince Weaver.

Test can currently return one of 3 states: ok, fail, skip.
The ok and fail states are self-explanatory. The skip state means that
some of the conditions for running the test was not met, making it
impossible to even run the test. For instance, if the hardware doesn't
support the 'precise' level required by a test, it will be skipped.

It just will add the O= builddir to PYTHONPATH and try to 'use perf',
which will, in verbose mode show the python backtrace with the missing
symbols, such as in the problem fixed in the patch after this one:
# perf test -v 15
15: Try 'use perf' in python, checking link problems :
--- start ---
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /home/acme/git/build/perf//python/perf.so: undefined symbol: test_attr__enabled
---- end ----

As they are used from diff and event group report, add a test case to
verify their behaviors.
In this test I made a fake machine and two evsel. Each evsel got 10
samples (so hist entries) - 5 are common and the rests are not. So
after hists__match() both of them will have 5 entries with pair set.
And the second evsel has a collapsed entry so that the total number is 9
- I made it in order to simulate more realistic case. Thus after
hists__link the first entry will have 14 entries - 5 are common (w/
pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the
second entry will have 9 entries all have its pair.
