Auto merge of #9572 - Nilstrieb:as-ptr-cast-mut, r=dswij
Add `as_ptr_cast_mut` lint This lint detects calls to a `&self`-taking `as_ptr` method, where the result is then immediately cast to a `*mut T`. Code like this is probably invalid, as that pointer will not have write permissions, and `*mut T` is usually used to write through. Examples of broken code with this pattern: https://miri.saethlin.dev/ub?crate=lol_alloc&version=0.1.3 https://miri.saethlin.dev/ub?crate=sophon-wasm&version=0.19.0 https://miri.saethlin.dev/ub?crate=polars-core&version=0.24.2 https://miri.saethlin.dev/ub?crate=ach-cell&version=0.1.17 changelog: Add [`as_ptr_cast_mut`]
