unique_ptr(unique_ptr&& __u) _NOEXCEPT
Obviously these won't be part of the final patch. This is just an easy way to figure out which methods are important (both for me and the pass).
In Swift, there's a `@_semantics` decorator that can be applied to functions so the compiler can apply specific optimizations. Is there anything like that in clang? If not, would something like that be welcome and/or possible? If so, I'm happy to implement it.
