perf/test: Speed up test case perf annotate basic tests
perf test 70 takes a long time. One culprit is the output of command
perf annotate. Per default enabled are
- demangle symbol names
- interleave source code with assembly code.
Disable demangle of symbols and abort the annotation
after the first 250 lines.
This speeds up the test case considerable, for example
on s390:
Output before:
# time perf test 70
70: perf annotate basic tests : Ok
.....
real 2m7.467s
user 1m26.869s
sys 0m34.086s
#
Output after:
# time perf test 70
70: perf annotate basic tests : Ok
real 0m3.341s
user 0m1.606s
sys 0m0.362s
