   void CheckArgAlignment(SourceLocation Loc, NamedDecl *FDecl,
-                         StringRef ParamName, QualType ArgTy, QualType ParamTy);
+                         StringRef ParamName, QualType ArgTy, QualType ParamTy,
+                         const Expr *Arg = nullptr);

Thanks, that is something I overlooked. 

It seems like I can do this everywhere except the call from `Sema::CheckConstructorCall`. Trying to figure out whether it's something I'm missing.
