2020-08-22Auto merge of #75171 - amosonn:new_zeroed_slice, r=Amanieubors-15/+58
New zeroed slice Add to #63291 the methods ```rust impl<T> Box<[T]> { pub fn new_zeroed_slice(len: usize) -> Box<[MaybeUninit<T>]> {…} } impl<T> Rc<[T]> { pub fn new_zeroed_slice(len: usize) -> Rc<[MaybeUninit<T>]> {…} } impl<T> Arc<[T]> { pub fn new_zeroed_slice(len: usize) -> Arc<[MaybeUninit<T>]> {…} } ``` as suggested in https://github.com/rust-lang/rust/issues/63291#issuecomment-605511675 . Also optimize `{Rc, Arc}::new_zeroed` to use `alloc_zeroed`, otherwise they are no more efficient than using `new_uninit` and zeroing the memory manually (which was the original implementation).

2020-07-30Rollup merge of #74782 - vorner:weak-into-raw-cnt-doc, r=dtolnayManish Goregaokar-11/+11
Don't use "weak count" around Weak::from_raw_ptr As `Rc/Arc::weak_count` returns 0 when having no strong counts, this could be confusing and it's better to avoid using that completely. Closes #73840.
