967c3880d8 Rollup merge of #33815 - carols10cents:trait-documentation-clarifications, r=steveklabnik 
Trait documentation clarifications

Hi! I've felt a bit of friction lately in figuring out how to write custom implementations of the `derive`able traits, so I decided to add to the docs :)

The docs for `Copy` are already excellent-- clear, useful sections that I only reordered a bit-- they're now:

* General explanation
* When can my type be `Copy`?
* When can my type _not_ be `Copy`?
* When should my type be `Copy`?
* Derivable
* How can I implement `Copy`?

I didn't add all these sections for all the traits, but I did make sure all the derivable traits had a consistent "Derivable" section that explained what the derived implementation does and a "How can I implement" section that has an example.

Please check me for correctness-- I tried to do research to make sure I was saying accurate things but I'm still learning! ❤️ I'd also love suggestions on information to add that is still missing-- I think these traits are important and deserve to have awesome docs!

Fix `asm-misplaced-option` on ARM/AArch64

This fixes rust-lang/rust#33737. Of course, since we don't run `make check` for ARM cross builds, you probably won't notice it.

Fix handling of FFI arguments

cc @alexcrichton @rust-lang/core

The strategy employed here was to essentially change code we generate from

```llvm
  %s = alloca %S ; potentially smaller than argument, but never larger
  %1 = bitcast %S* %s to { i64, i64 }*
  store { i64, i64 } %0, { i64, i64 }* %1, align 4
```

to

```llvm
  %1 = alloca { i64, i64 } ; the copy of argument itself
  store { i64, i64 } %0, { i64, i64 }* %1, align 4
  %s = bitcast { i64, i64 }* %1 to %S* ; potentially truncate by casting to a pointer of smaller type.
```

                    below, are usable today through the lazy-static crate on
                    stable Rust today. Additionally, we'd like the non-static
                    versions to be directly usable in a static context one day,

Fixes to mir dataflow

Fixes to mir dataflow

This collects a bunch of changes to `rustc_borrowck::borrowck::dataflow` (which others have pointed out should probably migrate to some crate that isn't tied to the borrow-checker -- but I have not attempted that here, especially since there are competing approaches to dataflow that we should also evaluate).

These changes:
 1. Provide a family of related analyses: MovingOutStatements (which is what the old AST-based dataflo computed), as well as MaybeInitialized, MaybeUninitalized, and DefinitelyInitialized.
   * (The last two are actually inverses of each other; we should pick one and drop the other.)
 2. Fix bugs in the pre-existing analysis implementation, which was untested and thus some obvious bugs went unnoticed, which brings us to the third point:
 3. Add a unit test infrastructure for the MIR dataflow analysis.
   * The tests work by adding a new intrinsic that is able to query the analysis state for a particular expression (technically, a particular L-value).
   * See the examples in compile-fail/mir-dataflow/inits-1.rs and compile-fail/mir-dataflow/uninits-1.rs
   * These tests are only checking the results for MaybeInitialized, MaybeUninitalized, and DefinitelyInitialized; I am not sure if it will be feasible to generalize this testing strategy to the MovingOutStatements dataflow operator.

5229e0efb3 Auto merge of #33602 - eddyb:no-trans--check, r=michaelwoerister 
Save metadata even with -Z no-trans (e.g. for multi-crate cargo check).

Removes the item symbol map in metadata, as we can now generate them in a deterministic manner.
The `-Z no-trans` change lets the LLVM passes and linking run, but with just metadata and no code.
It fails while trying to link a binary because there's no `main` function, which is correct but not good UX.

There's also no way to easily throw away all of the artifacts to rebuild with actual code generation.
We might want `cargo check` to do that using cargo-internal information and then it would just work.
