Since CPython seems to be successfully building and being fuzzed in OSS-Fuzz, it's time to add some more interesting fuzzing targets. This PR does the following:
int(x)fuzz target. Since python supports arbitrarily large integers, there is a ratherboring case that is essentially
int("9" * 100000)causing timeouts in this path.json.loads(x)for fuzzing.Potential reviewers: @gpshead @alex (skip-news label can be applied)
