Than McIntosh cfac62a1cc cmd/compile: fix bug in defer wrapping
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.
