Using a type alias for iterator implementations is fragile since this
exposes the implementation to users of the iterator, and any changes
could break existing code.
This commit changes the iterators of `VecMap` to use
proper new types, rather than type aliases. However, since it is
fair-game to treat a type-alias as the aliased type, this is a:
[breaking-change].
Part of #18469

A receiver will only ever get a single auto-reference. Previously arrays and strings would get two, e.g., [T] would be auto-ref'ed to &&[T]. This is usually apparent when a trait is implemented for `&[T]` and has a method takes self by reference. The usual solution is to implement the trait for `[T]` (the DST form).

The names expected and actual are not used anymore in the output. It also
removes the confusion that the argument order is the opposite of junit.
Bug #7330 is relevant.

One question is: should we start by warning, and only switch to hard error later? I think we discussed something like this in the meeting.

Was testing rustup on a very minimal Debian installation and got errors during the install process (error occurred in `install.sh` of the Rust nightly.)
Noticed that Rustup was downloading the i686 nightly instead of x86-64. Installing `file` fixed the problem, and this patch adds the probe to ensure file is installed before attempting to use it.
There may still be an issue with the i686 installation, I did not investigate further.

This commit performs a second pass stabilization of the `std::default` module.
The module was already marked `#[stable]`, and the inheritance of `#[stable]`
was removed since this attribute was applied. This commit adds the `#[stable]`
attribute to the trait definition and one method name, along with all
implementations found in the standard distribution.
This commit takes a second pass through the `std::mem` module for stabilization.
The only remaining non-stable items in this module were `forget`, `transmute`,
`copy_lifetime`, and `copy_lifetime_mut`.
The `forget` and `transmute` intrinsics themselves were marked `#[stable]` to
propgate into the `core::mem` module so they would be marked stable.
The `copy_lifetime` functions were left `unstable`, but `Sized?` annotations
were added to the parameters to allow more general use with DSTs.
The `size_of_val`, `min_align_of_val`, and `align_of_val` functions would like
to grow `Sized?` bounds, but this is a backwards compatible change that
currently ICEs the compiler, so this change was not made at this time.
Finally, the module itself was declared `#![stable]` in this pass.
This commit collapses the various prelude traits for slices into just one trait:
* SlicePrelude/SliceAllocPrelude => SliceExt
* CloneSlicePrelude/CloneSliceAllocPrelude => CloneSliceExt
* OrdSlicePrelude/OrdSliceAllocPrelude => OrdSliceExt
* PartialEqSlicePrelude => PartialEqSliceExt
