Rollup merge of #40731 - sfackler:vec-from-iter-spec, r=aturon
Specialize Vec::from_iter for vec::IntoIter It's fairly common to expose an API which takes an `IntoIterator` and immediately collects that into a vector. It's also common to buffer a bunch of items into a vector and then pass that into one of these APIs. If the iterator hasn't been advanced, we can make this `from_iter` simply reassemble the original `Vec` with no actual iteration or reallocation. r? @aturon
