This patch adds tracking which modules are instrumented and which are not.  On macOS, instrumented modules link against the ASan/TSan/... dylib, so we can just check if such a load command exists or not.

This is needed to implement a feature that needs to know if an interceptor is called from instrumented code or not (then it's likely a system library).  The patch for that will follow.
