Fixes a regression from #4913 which causes items to be exanded with spans lacking expn_info from the context's current backtrace.

|item| items.push(item));
decorator_items.push_all(items.move_iter()
.flat_map(|item| expand_item(item, fld).move_iter())
.collect());

Could we avoid collect() here? I don't know if there's a vec method that takes an Iterator<T>, but if not, there probably should be.

It's called .extend

r=me with .extend. (What a subtle thing to track down! Nice work.)

(Oh, it seems Vec doesn't implement Extendable...)

It will be implemented when #12673 lands.

We're using SmallVec anyway, so I will implement extend for that.

Yeah, this was a total pain to track down. Sadly I couldn't think of a nice way to test it either.
