Jump threading stores values as `u128` (`ScalarInt`) and does its
comparisons for equality as integer comparisons.
This works great for integers. Sadly, not everything is an integer.
Floats famously have wonky equality semantcs, with `NaN!=NaN` and
`0.0 == -0.0`. This does not match our beautiful integer bitpattern
equality and therefore causes things to go horribly wrong.
While jump threading could be extended to support floats by remembering
that they're floats in the value state and handling them properly,
it's signficantly easier to just disable it for now.

Add a test for #107975
The int is zero. But also not zero. This is so much fun.
This is a part of #105107.
Initially I was going to just rebase #108445, but quite a few things changed since then:
* The [mcve](https://github.com/rust-lang/rust/issues/105787#issuecomment-1750112388) used for #105787 got fixed.[^upd2]
* You can't just `a ?= b` for #107975 anymore. Now you have to `a-b ?= 0`. This is what this PR does. As an additional flex, it show that three ways of converting a pointer to its address have this issue:
1. `as usize`
2. `.expose_provenance()`
3. `.addr()`
* #108425 simply got fixed. Yay.
As an aside, the naming for `addr_of!` is quite unfortunate in context of provenance APIs. Because `addr_of!` gives you a pointer, but what provenance APIs refer to as "address" is the `usize` value. Oh well.
UPD1: GitHub is incapable of parsing #107975 in the PR name, so let's add it here.
[^upd2]: UPD2: [The other mcve](https://github.com/rust-lang/rust/issues/105787#issue-1500501670) does not work anymore either, saying "this behavior recently changed as a result of a bug fix; see rust-lang/rust#56105 for details."

More accurate suggestion for `-> Box<dyn Trait>` or `-> impl Trait`
When encountering `-> Trait`, suggest `-> Box<dyn Trait>` (instead of `-> Box<Trait>`.
If there's a single returned type within the `fn`, suggest `-> impl Trait`.

Update jsondocck directives to follow ui_test-style
Context: Comment chain in #125813.
Follow-up to #126788.
Use the same temporary approach of "double parsing" until we figure out how we want to support compiletest/ui_test directive "add-ons" for child test runners like HtmlDocCk and JsonDocCk.
I didn't touch much of jsondocck because I want to refactor it some other time (for robustness, maintainability and better diagnostics; basically by following a similar design of my WIP HtmlDocCk-next, cc #125780).

Lazy type aliases: Diagostics: Detect bivariant ty params that are only used recursively
Follow-up to errs's #127871. Extends the logic to cover LTAs, too, not just ADTs.
This change only takes effect with the next-gen solver enabled as cycle errors like
the one we have here are fatal in the old solver. That's my explanation anyways.

`C-cmse-nonsecure-call`: improved error messages
tracking issue: #81391
issue for the error messages (partially implemented by this PR): #81347
related, in that it also deals with CMSE: https://github.com/rust-lang/rust/pull/127766
When using the `C-cmse-nonsecure-call` ABI, both the arguments and return value must be passed via registers. Previously, when violating this constraint, an ugly LLVM error would be shown. Now, the rust compiler itself will print a pretty message and link to more information.

CFI: Support provided methods on traits
Provided methods currently don't get type erasure performed on them because they are not in an `impl` block. If we are instantiating a method that is an associated item, but *not* in an impl block, treat it as a provided method instead.

Disable run-make/split-debuginfo test for RISC-V 64
Together with `@Hoverbear,` we've been improving the state of the riscv64gc-unknown-linux-gnu target.
This is in relation to https://github.com/rust-lang/rust/pull/125220 where `tests/ui/debuginfo/debuginfo-emit-llvm-ir-and-split-debuginfo.rs` was disabled for RISC-V 64 in that another test, `tests/run-make/split-debuginfo` also needs to be disabled due to https://github.com/llvm/llvm-project/issues/56642 and the changes made in https://github.com/rust-lang/rust/pull/120518.
This test appears to be a host test, not a target test, so it isn't seen failing in https://github.com/rust-lang/rust/pull/126641, however, we are in the process of testing host tools for riscv64-gc-unknown-linux-gnu so this test has now been noticed to be a problem.

interpret: add sanity check in dyn upcast to double-check what codegen does
For dyn receiver calls, we already have two codepaths: look up the function to call by indexing into the vtable, or alternatively resolve the DefId given the dynamic type of the receiver. With debug assertions enabled, the interpreter does both and compares the results. (Without debug assertions we always use the vtable as it is simpler.)
This PR does the same for dyn trait upcasts. However, for casts *not* using the vtable is the easier thing to do, so now the vtable path is the debug-assertion-only path. In particular, there are cases where the vtable does not contain a pointer for upcasts but instead reuses the old pointer: when the supertrait vtable is a prefix of the larger vtable. We don't want to expose this optimization and detect UB if people do a transmute assuming this optimization, so we cannot in general use the vtable indexing path.

Don't allow unsafe statics outside of extern blocks
This PR fixes a regression where we allowed `unsafe static` items in top-level modules (i.e. outside of `unsafe extern` blocks).
It's harder IMO to integrate this into the `check_item_safety` function, so I opted to just put this check on the `static` item itself.
Beta version of this lives at #127944.

When finding item gated behind a `cfg` flag, point at it
Previously we would only mention that the item was gated out, and opportunisitically mention the feature flag name when possible. We now point to the place where the item was gated, which can be behind layers of macro indirection, or in different modules.

Parser: Suggest Placing the Return Type After Function Parameters
Fixes #126311
This PR suggests placing the return type after the function parameters when it's misplaced after a `where` clause.
This also tangentially improves diagnostics for cases like [this](https://github.com/veera-sivarajan/rust/blob/86d6f1312a77997ef994240e716288d61a343a6d/tests/ui/parser/issues/misplaced-return-type-without-where-issue-126311.rs#L1C1-L1C28) and adds doc comments for `parser::AllowPlus`.
