Bug description:
The Tools/scripts/summarize_stats.py script currently has the ability to save stats to a .json file so that collected stats can later be compared to another set of collected stats. Unfortunately, this comparison must be performed on the same version of Python that collected the stats, since information about specialized instructions and stats types are collected at runtime during the comparison (from the opcode module and by scraping the source code). Failure to do so may either break, or, worse, silently create incorrect results. If this information was instead stored in the .json file, the comparison could be formed on any recent enough build of Python, which is particularly important for the benchmarking infrastructure, where we don't want to have to checkout or rebuild specific versions of Python just to create derived comparative data.
