<pre>In include/llvm/ADT/None.h, llvm::None is defined as follows:
namespace llvm {
enum class NoneType { None };
const NoneType None = None;
}
Clearly the intention is for the initializer to name the enumerator 'None', but
it actually names the variable 'None', which means the resulting of value of
the variable 'None' is unspecified (rather than the intended NoneType::None).
The definition should instead be:
namespace llvm {
enum class NoneType { None };
const NoneType None = NoneType::None;
}</pre>
