UpdateTestChecks has a make_analyzer_generalizer to replace pointer addressess from the debug output of LAA with a pattern, which is an acceptable solution when there is one RUN line. However, when there are multiple RUN lines with a common pattern, UTC fails to recognize common output due to mismatched pointer addresses. Instead of hacking UTC scrub the output before comparing the outputs from the different RUN lines, fix the issue once and for all by making LAA not output unstable pointer addresses in the first place. The removal of the now-dead make_analyzer_generalizer is left as a non-trivial exercise for a follow-up.
