We do still use them in places, protected by
LLVM_HAS_VARIADIC_TEMPLATES - usually providing a fallback
non-variadic implementation. That way users with variadic support in
their compilers get better error messages, etc, (and out-of-tree
library users of any such APIs get the desired behavior without being
limited by MSVC2012).
