Moving from llvm 7.0 to 8.0 functions marked `__attribute__((used))
__attribute__ ((__visibility__("default")))` are not linked into final
executable under these circumstances:
* Function is in static library
* `-flto=thin` is used (`-flto` or no lto works as expected)
* Function is not referenced from other functions that are alive
* Target: `x86_64-apple-darwin11`
