[Sema] If CheckPlaceholderExpr rewrites the initializer of an auto
variable during auto type deduction, use the rewritten initializer when
performing initialization of the variable.
This silences spurious -Warc-repeated-use-of-weak warnings that are
issued when the initializer uses a weak ObjC pointer.
