**Breaking change**: `VecMap::into_iter` now consumes the `VecMap`. To fix it you should pass the VecMap by value instead of by reference.

After PR #19766 added implicit coersions `*mut T -> *const T`, the explicit casts can be removed.
(The number of such casts turned out to be relatively small).
There are a large number of places that incorrectly refer
to deriving in comments, instead of derives.
If someone could look at src/etc/generate-deriving-span-tests.py,
I'm not sure how those tests were passing before/if they were.
This fixes the issues mentioned in https://github.com/rust-lang/rust/pull/21236, as well as the one https://github.com/rust-lang/rust/issues/21230 where `CFG_BOOTSTRAP_KEY` was being set to simply 'N'. It changes the build such that `RUSTC_BOOTSTRAP_KEY` is only exported on -beta and -stable, so that the behavior of the -dev, -nightly, and snapshot compilers is the same everywhere.
Haven't run it completely through 'make check' yet, but the I have verified that the aforementioned issues are fixed.

The collections were promoted to stable by mistake and do not match RFC 509.
This reverts the stability back to unstable.
[breaking-change] since previously stable API became unstable.
Fixes#21193
...to make it slightly clearer that there's not much point in boxing a vec.
On a different note, I read the contribution guidelines (https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#pull-request-procedure) which say I should update the copyright date for this file. But I can see that nobody else has done this so far this year, despite there being a fair number of commits.
Does that instruction need removing?
By returning the passed value black_box can be used on data being
passed to a function being benchmarked. This ensures the compiler
does not optimize the function for the input which could result in
the entire function being optimized away.
This gets rid of the 'experimental' level, removes the non-staged_api
case (i.e. stability levels for out-of-tree crates), and lets the
staged_api attributes use 'unstable' and 'deprecated' lints.
This makes the transition period to the full feature staging design
a bit nicer.
