I believe in the current cmake build that `-fvisibility=hidden` is only passed into compile actions in lib/Target/*. The intention is to eliminate backend library symbols, but expose all other LLVM symbols. It's a coarse grained way of annotating the LLVM API. I'm guessing the problem is that, for those compiles, they see `llvm::Function` as a hidden class, when really it is intended to be visible.
