This forces callers to use std::move when calling it. It is somewhat odd to have code with std::move that doesn't always move, but it is also odd to have code without std::move that sometimes moves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217049 91177308-0d34-0410-b5e6-96231b3b80d8
