Initial version of the correctness fuzzer harness for manual testing and experiments. For automated usage, some outstanding TODOs are left in the code. E.g. - Hash source file names in error case - Bundle script in out directory with executables - Some suppressions are tied to already fixed bugs. We'll keep it like that for now to test removing those suppressions in production later.
