Rollup merge of #121840 - oli-obk:freeze, r=dtolnay
...
Expose the Freeze trait again (unstably) and forbid implementing it manually
non-emoji version of https://github.com/rust-lang/rust/pull/121501
cc #60715
This trait is useful for generic constants (associated consts of generic traits). See the test (`tests/ui/associated-consts/freeze.rs`) added in this PR for a usage example. The builtin `Freeze` trait is the only way to do it, users cannot work around this issue.
It's also a useful trait for building some very specific abstrations, as shown by the usage by the `zerocopy` crate: https://github.com/google/zerocopy/issues/941

T-lang signed off on reexposing this unstably: https://github.com/rust-lang/rust/pull/121501#issuecomment-1969827742

Rollup merge of #97675 - nvzqz:unsized-needs-drop, r=dtolnay
...
Make `std::mem::needs_drop` accept `?Sized`
This change attempts to make `needs_drop` work with types like `[u8]` and `str`.
This enables code in types like `Arc<T>` that was not possible before, such as https://github.com/rust-lang/rust/pull/97676 .
