If one does not care about the guarantees about how they can be moved by
optimizations, it should be trivial to implement these. But if implemented, we
should of course try to hook them up with whatever attributes necessary to give
them the right behaviour.
These are necessary in order to build C++ code in MSVC mode for ARM using the
MSVC C++ headers.
