Clang appears to have an issue with visibility of enums included into a module GMF.
```
// decls.h
enum {
SomeName,
};
```
```
// module.mpp
module;
#include "decls.h"
export module mod;
```
```
// consumer.cpp
import mod;
auto a = SomeName;
```
This compiles without error - I believe incorrectly. Other implementations agree that `SomeName` is not in scope within `consumer.cpp`.
Note that Clang agrees with the other implementations under `-fmodules-reduced-bmi`. Presumably this implies that Clang is making the values visible to name lookup when the enum itself is reachable through the BMI. I couldn't find wording specifically for this case, but it certainly seems wrong intuitively.
