LGTM w/ nit



================
Comment at: clang/lib/Driver/SanitizerArgs.cpp:1091
 
+  if (Sanitizers.has(SanitizerKind::FuzzerNoLink)) {
+    CmdArgs.push_back("-fno-builtin-memcmp");
----------------
Nit - add a comment here mentioning the libfuzzer interceptors, and that other sanitizers normally do this by propagating IR attributes.
