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

[Akira Hatanaka via Phabricator via cfe-commits]

ahatanak added a comment.

We can make `DeduceVariableDeclarationType` return the rewritten expression and 
replace `Init` in `Sema::AddInitializerToDecl` with it.

Alternatively, we can keep a set of `ObjCPropertyRefExpr`s passed to 
`recordUseOfWeak` (the original `ObjCPropertyRefExpr`, if it was rebuilt in 
SemaPseudoObject.cpp) and avoid recording the use of a weak variable if the 
expression is passed the second time.
