Explanation: Fixes an issue where the generated reverse interop header would not compile for nested classes when library evolution is turned off. Scope: C++ reverse interop for nested classes for non-opaque types. Issue: rdar://147882976 Risk: Low, the fix is fairly targeted. While it does affect other (non-nested type) scenarios, those changes are fairly straightforward making some names fully qualified. Moreover, that is well tested in our test suite. Testing: Added tests to test suite Reviewer: @egorzhdan
