So far we used to ignore exception if DAR points outside of user
specified range. But now we are ignoring it only if actual load/store
range does not overlap with user specified range. Include selftests
for the same:
# ./tools/testing/selftests/powerpc/ptrace/perf-hwbreak
...
TESTED: No overlap
TESTED: Partial overlap
TESTED: Partial overlap
TESTED: No overlap
TESTED: Full overlap
success: perf_hwbreak
