Dokyung Song 831ae45e3d Recommit "[libFuzzer] Link libFuzzer's own interceptors when other compiler runtimes are not linked." 
Summary: libFuzzer intercepts certain library functions such as memcmp/strcmp by defining weak hooks. Weak hooks, however, are called only when other runtimes such as ASan is linked. This patch defines libFuzzer's own interceptors, which is linked into the libFuzzer executable when other runtimes are not linked, i.e., when -fsanitize=fuzzer is given, but not others.

The patch once landed but was reverted in 8ef9e2bf35 due to an assertion failure caused by calling an intercepted function, strncmp, while initializing the interceptors in fuzzerInit(). This issue is now fixed by calling libFuzzer's own implementation of library functions (i.e., internal_*) when the fuzzer has not been initialized yet, instead of recursively calling fuzzerInit() again.
