c++ interop
Explanation: Fixes an issue where the generated reverse interop header would not compile for nested types when library evolution is off. While this is a bug in a new feature in 6.1, users upgrading from 6.0 to 6.1 can see this as a regression because the new constructs that we started to expose to the interop header in 6.1 will trigger the compilation error. 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 straightforward making some names fully qualified. Moreover, that is well tested in our test suite.
