tests: introduce check-perf-code.py to add extra checks on perf.py
This patch introduces tests/check-perf-code.py as a preparation for
adding extra checks on contrib/perf.py in subsequent patches (mainly,
for historical portability).
At this change, check-perf-code.py doesn't add any extra check, and is
equal to check-code.py. This makes subsequent patch focus only on
adding an extra check on perf.py check-perf-code.py.
check-perf-code.py adds extra checks on perf.py by wrapping
contrib/check-code.py, because "filtering" by check-code.py (e.g.
normalize characters in string literal or comment line) is useful to
simplify regexp for check, and avoid false positive matching.
