The defer wrapping feature added to the compiler's "order" phase creates temporaries into which it copies defer arguments. If one of these temps is large enough that we place it into the defer closure by address (as opposed to by value), then the temp in question can't be reused later on in the order phase, nor do we want a VARKILL annotation for it at the end of the current block scope. Test written by Cherry. Updates #40724.
