Revert Vec/Rc storage reuse opt Remove the optimization for using storage added by #104205. The perf wins were pretty small, and it relies on non-guarenteed behaviour. On platforms that don't implement shrinking in place, the performance will be significantly worse. While it could be gated to platforms that do this (such as GNU), I don't think it's worth the overhead of maintaining it for very small gains. (#104565, #104563) cc `@RalfJung` `@matthiaskrgr` Fixes #104565 Fixes #104563 |
