Rollup merge of #89726 - jkugelman:must-use-alloc-constructors, r=joshtriplett
Add #[must_use] to alloc constructors Added `#[must_use]`. to the various forms of `new`, `pin`, and `with_capacity` in the `alloc` crate. No extra explanations given as I couldn't think of anything useful to add. I figure this deserves extra scrutiny compared to the other PRs I've done so far. In particular: * The 4 `pin`/`pin_in` methods I touched. Are there legitimate use cases for pinning and not using the result? Pinning's a difficult concept I'm not very comfortable with. * `Box`'s constructors. Do people ever create boxes just for the side effects... allocating or zeroing out memory? Parent issue: #89692 r? ``@joshtriplett``
