Trying to use members of C++ private base classes from Swift causes an assertion failure in ClangImporter:
```
<build dir>/swift/lib/swift/macosx/arm64/libcxxshim.h:2:66: error: cannot cast 'A' to its private base class 'B'
To __swift_interopStaticCast(From from) { return static_cast<To>(from); }
^
```
Such members should not be exposed.
