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

================
Comment at: lib/Sema/SemaType.cpp:8127
 QualType Sema::BuildDecltypeType(Expr *E, SourceLocation Loc,
                                  bool AsUnevaluated) {
   ExprResult ER = CheckPlaceholderExpr(E);
----------------
I couldn't assert here that `E` isn't a placeholder since there are several 
call sites that call this function and there are code paths that don't call 
`Sema::ActOnDecltypeExpression` before reaching this point.
