Rollup merge of #99436 - Nilstrieb:toggle-box-noalias, r=fee1-dead
Add flag to configure `noalias` on `Box<T>` The aliasing rules of `Box<T>` are still not decided, but currently, `Box<T>` is unique and gets `noalias`. To aid making an informed decision about the future of `Box<T>`, this PR adds a flag `-Zbox-noalias` to configure `noalias` for `Box<T>` (for example, for benchmarking). The same flag already exists for `&mut T` `noalias`, where it was added because it was the problem of various miscompilations in LLVM. For more information, see rust-lang/unsafe-code-guidelines#326
