You are right, `hasCXXExplicitFunctionObjectParameter()` should imply `isInstance()`, so `isInstance()` is no longer needed. Passed `check-clangd` on my own build.

```diff
      if (const CXXMethodDecl *Method =
              dyn_cast_or_null<CXXMethodDecl>(Callee.Decl))
-       if (Method->isInstance() &&

+       if (IsFunctor || Method->hasCXXExplicitFunctionObjectParameter())
          Args = Args.drop_front(1);
```
