Since Emscripten uses musl libc internally. Non-functional change: all LFS64 symbols were aliased to their non-LFS64 counterparts in rust-lang/libc@7c952dc.
Align it with musl, which also prefers using lstat() here.

Note that above the structured suggestion also includes completely removing the manual `impl`, but the rendering doesn't.

…bank E0277: suggest dereferencing function arguments in more cases This unifies and generalizes some of the logic in `TypeErrCtxt::suggest_dereferences` so that it will suggest dereferencing arguments to function/method calls in order to satisfy trait bounds in more cases. Previously it would only fire on reference types, and it had two separate cases (one specifically to get through custom `Deref` impls when passing by-reference, and one specifically to catch rust-lang#87437). I've based the new checks loosely on what's done for `E0308` in `FnCtxt::suggest_deref_or_ref`: it will suggest dereferences to satisfy trait bounds whenever the referent is `Copy`, is boxed (& so can be moved out of the boxes), or is being passed by reference. This doesn't make the suggestion fire in contexts other than function arguments or binary operators (which are in a separate case that this doesn't touch), and doesn't make it suggest a combination of `&`-removal and dereferences. Those would require a bit more restructuring, so I figured just doing this would be a decent first step. Closes rust-lang#90997

Some small nits to the borrowck suggestions for mutating a map through index
1. Suggesting users to either use `.insert` or `.get_mut` (which do totally different things) can be a bit of a footgun, so let's make that a bit more nuanced.
2. I find the suggestion of `.get_mut(|val| { *val = whatever; })` to be a bit awkward. I changed this to be an if-let instead.
3. Fix a bug which was suppressing the structured suggestion for some mutations via the index operator on `HashMap`/`BTreeMap`.
