Richard Smith 72db888389 PR35039: Materialize temporary objects before wrapping them in an

Richard Smith 122f88d481 [c++17] P0135R1: Guaranteed copy elision.
When an object of class type is initialized from a prvalue of the same type

instead of inserting a redundant elidable call to a copy constructor.
