Currently LLVM CFI tries to use an implicit blacklist file, currently in
/usr/lib64/clang/<version>/share. If the file is not there, LLVM happily
continues, which causes CFI to add checks to files/functions that are known to
fail, generating binaries that fail. This CL causes LLVM to die (I hope) if it
can't find these implicit blacklist files.
