[Sema] Add implicit members even for invalid CXXRecordDecls Summary: It should be safe, since other code paths are already generating implicit members even in invalid CXXRecordDecls (e.g. lookup). If we don't generate implicit members on CXXRecordDecl's completion, they will be generated by next lookup of constructors. This causes a crash when the following conditions are met: - a CXXRecordDecl is invalid, - it is provided via ExternalASTSource (e.g. from PCH), - it has inherited constructors (they create ShadowDecls), - lookup of its constructors was not run before ASTWriter serialized it. This may require the ShadowDecls created for inherited constructors to be removed from the class, but that's no longer possible since class is provided by ExternalASTSource. See provided lit test for an example.
