Enable Vec's calloc optimization for Option<NonZero> Someone on discord noticed that `vec![None::<NonZeroU32>; N]` wasn't getting the optimization, so here's a PR 🙃 We can certainly do this in the standard library because we know for sure this is ok, but I think it's also a necessary consequence of documented guarantees like those in https://doc.rust-lang.org/std/option/#representation and https://doc.rust-lang.org/core/num/struct.NonZeroU32.html It feels weird to do this without adding a test, but I wasn't sure where that would belong. Is it worth adding codegen tests for these? |
