What do you think about the following tweak:

```
SmallVector<const ParamVarDecl *> ForwardedParamsStorage;
ArrayRef<const ParamVarDecl *> ForwardedParams;
if (Callee.Decl) {
  ForwardedParamsStorage = resolveForwardingParameters(Callee.Decl);
  ForwardedParams = maybeDropCxxExplicitObjectParameters(ForwardedParamsStorage);
} else {
  ForwardedParams = Params;
}
