[PATCH] D55662: [Sema][ObjC] Do not warn about repeated uses of weak variables when the variables are accessed in an unevaluated context.

Sorry, please ignore my previous comment. I was looking at the wrong place.

The following code reaches `Sema::BuildDecltypeType` without going through `ActOnDecltypeExpression`:

  template <typename T>
  void overloaded_fn(T);
  decltype(auto) v5 = &overloaded_fn<int>;

`Sema::BuildDecltypeType` is called from `Sema::DeduceAutoType`, so calling `CheckPlaceholderExpr ` there should fix the assert when the test case above is compiled.
