This is the patch I split out of https://reviews.llvm.org/D64464.

The cleanup is pushed in `EmitCallExpr` and `EmitObjCMessageExpr` so that the destructor is called to destruct function call and ObjC message returns. I also added test cases for block function calls since the patch in https://reviews.llvm.org/D64464 wasn't handling that case correctly.
