In `InitListChecker::FillInEmptyInitForField`, we will create a
`CXXDefaultInitExpr` and fill in empty field `const A a& = A{};` for `for (auto
&&x : B{}) {}` . Also there will have a `ExprWithCleanup` in
`CXXDefaultInitExpr`.
This is what I know about the difference in AST between the two cases, when I
change the ExtendingDecl of `MaterializedTemporaryExpr`, it does not generate
correct cleanups in CodeGen.
