Given a list L of functions to identify and a small list of
candidates C, this tool will attempt to automatically identify matches
by checking each function in L against each function in C.
Very slow, but this should work well enough for small lists.
This makes it possible to catch regressions for non-matching functions,
especially those that only have minor issues.
This also reclassifies some minor non-matchings as major non-matchings
whenever it's really not obvious to see that they are equivalent.
