Auto merge of #111807 - erikdesjardins:noalias, r=oli-obk
[rustc_ty_utils] Treat `drop_in_place`'s *mut argument like &mut when adding LLVM attributes This resurrects PR #103614, which has sat idle for a while. This could probably use a new perf run, since we're on a new LLVM version now. r? `@oli-obk` cc `@RalfJung` --- LLVM can make use of the `noalias` parameter attribute on the parameter to `drop_in_place` in areas like argument promotion. Because the Rust compiler fully controls the code for `drop_in_place`, it can soundly deduce parameter attributes on it. In #103957, Miri was changed to retag `drop_in_place`'s argument as if it was `&mut`, matching this change.
