do the right thing with mixed-visibility symbols, so disable the visibility optimization where that's possible, i.e. with template classes (since it's possible that an arbitrary template might be subject to an explicit instantiation elsewhere). 447.dealII actually does this. I've put the code under an option that's currently not hooked up to anything. llvm-svn: 110374
