The PR reapply https://github.com/llvm/llvm-project/pull/97308. - Implement [CWG1815](https://wg21.link/CWG1815): Support lifetime extension of temporary created by aggregate initialization using a default member initializer. - Fix crash that introduced in https://github.com/llvm/llvm-project/pull/97308. In `InitListChecker::FillInEmptyInitForField`, when we enter rebuild-default-init context, we copy all the contents of the parent context to the current context, which will cause the `MaybeODRUseExprs` to be lost. But we don't need to copy the entire context, only the `DelayedDefaultInitializationContext` was required, which is used to build `SourceLocExpr`, etc. --------- Signed-off-by: yronglin <yronglin777@gmail.com>
