[PATCH] D83494: [libFuzzer] Link libFuzzer's own interceptors when other compiler runtimes are not linked.

[Dokyung Song via Phabricator via cfe-commits]

Ensure the fuzzer RT module is initialized at the beginning of the interceptors.

Interceptors can be called before __fuzzer_init is called. So I added a check at the beginning of the interceptors, which ensures that __fuzzer_init has been called before proceeding.
