msp430: remove the whole Atomic* API
PR #51953 enabled the Atomic*.{load,store} API on MSP430. Unfortunately,
the LLVM backend doesn't currently support those atomic operations, so this
commit removes the API and leaves instructions on how and when to enable it
in the future.
the second fixes compiling liballoc for msp430
closes#54511

Rustbuild passes `--message-format json` to the compiler invocations
which causes JSON to be emitted on stdout. Printing optimization fuel
messages to stdout breaks the json and causes Rustbuild to fail.
Work around this by emitting optimization fuel related messages on
stderr instead.
I removed the original file that more completely captured the original
crate's tests, as its source crate
(https://crates.io/crates/collection) is licensed under GPL3, and I
suspect that license is not loose enough for me to put into our repo
under our MIT/Apache licensing.
(Would it be an option to attach the GPL3 licesne to just the one
test? Probably. But do I want to bother with it that that point?
Nope!)

Make a bunch of trivial methods of NonNull be `#[inline]`
I was seeing super trivial methods not getting inlined in some of my builds, so I went ahead and just marked all the methods inline where it seemed appropriate.

back out bogus `Ok`-wrapping suggestion on `?` arm type mismatch
This suggestion was introduced in #51938 / 6cc78bf8d7 (while introducing different language for type errors coming from `?` rather than a `match`), but it has a lot of false-positives, and incorrect suggestions carry more badness than marginal good suggestions do goodness. I regret not doing this earlier. 😞Resolves#52537, resolves#54578.

Avoid unnecessary allocations in `float_lit` and `integer_lit`.
This commit avoids an allocation when parsing any float and integer
literals that don't involved underscores.
This reduces the number of allocations done for the `tuple-stress`
benchmark by 10%, reducing its instruction count by just under 1%.
miri engine: Stacked Borrows NG
For more refined tracking in miri, we do return untagged pointers from the memory abstraction after allocations and let the caller decide how to tag these.
Also refactor the `tag_(de)reference` hooks so they can be more easily called in the ref-to-place and place-to-ref methods, and reorder things in validation: validation calls ref-to-place which (when running in miri) triggers some checks, so we want to run it rather late and catch other problems first. We also do not need to redundantly check the ref to be allocated any more, the checks miri does anyway imply thath.
