M.dump() output (grepped for affected function)

I've attached a (minimized) build log that performs M.dump() when triggering
the 'Alias should have private, internal, linkonce, weak, linkonce_odr,
weak_odr, or external linkage!' in Verifier.cpp

This error does not occur when compiling without CFI.
