add `extern "C-cmse-nonsecure-entry" fn`
tracking issue #75835
in https://github.com/rust-lang/rust/issues/75835#issuecomment-1183517255 it was decided that using an abi, rather than an attribute, was the right way to go for this feature.
This PR adds that ABI and removes the `#[cmse_nonsecure_entry]` attribute. All relevant tests have been updated, some are now obsolete and have been removed.
Error 0775 is no longer generated. It contains the list of targets that support the CMSE feature, and maybe we want to still use this? right now a generic "this abi is not supported on this platform" error is returned when this abi is used on an unsupported platform. On the other hand, users of this abi are likely to be experienced rust users, so maybe the generic error is good enough.

Correct outdated object size limit
The comment here about 48 bit addresses being enough was written in 2016 but was made incorrect in 2019 by 5-level paging, and then persisted for another 5 years before being noticed and corrected.
The bolding of the "exclusive" part is merely to call attention to something I missed when reading it and doublechecking the math.

Disallow hidden references to mutable static
Closes #123060
Tracking:
- https://github.com/rust-lang/rust/issues/123758

The issue-112505-overflow test just extended a case of transmute-fail.rs
so simply put them in the same file.
Then we normalize away other cases of this.

simplify float::classify logic
I played around with the float-classify test in the hope of triggering x87 bugs by strategically adding `black_box`, and still the exact expression `@beetrees` suggested [here](https://github.com/rust-lang/rust/pull/129835#issuecomment-2325661597) remains the only case I found where we get the wrong result on x87. Curiously, this bug only occurs when MIR optimizations are enabled -- probably the extra inlining that does is required for LLVM to hit the right "bad" case in the backend. But even for that case, it makes no difference whether `classify` is implemented in the simple bit-pattern-based version or the more complicated version we had before.
Without even a single testcase that can distinguish our `classify` from the naive version, I suggest we switch to the naive version.

[bootstrap] Add support for building gcc and libgccjit
As `@eholk` summarized below:
> From my understanding, this change would add libgccjit as an optional component to the Rust distribution. This library is licensed under GPLv2 and currently we do not have any other components under that license so it would be a new license, and one that is generally more restrictive than the other licenses we use.
It'll greatly improve the experience for anyone wanting to work on the GCC backend from the compiler.
Should help with https://github.com/rust-lang/rust/issues/124172.
Will unblock #124353.

Add missing `needs-llvm-components` directives for run-make tests that need target-specific codegen
Without suitable `needs-llvm-components` directives, some run-make tests exercising target-specific codegen can fail if the LLVM used is built without the necessary components. Currently, the list is:
```
tests\run-make\print-target-list
tests\run-make\print-to-output
tests\run-make\print-cfg
tests\run-make\target-without-atomic-cas
```
This PR also skips tidy checks for revisions and `needs-llvm-components` for run-make tests since revisions are not supported.
Fixes #129390.
Fixes #127895.
cc ``@petrochenkov`` who noticed this, thanks! Would be great if you could confirm that this fixes the test errors for you locally.

Recent versions of wasm-tools are now Apache-2.0 or MIT or Apache-2.0
with the LLVM exception, rather than strictly Apache-2.0 with the LLVM
exception. The only component with the exception has moved to a new
dependency `wasi-preview1-component-adapter-provider`.

Port `run-make/libtest-json` and `run-make/libtest-junit` to rmake
Unlike #126773, this is just a straightforward port to `rmake`, without attempting to switch to compiletest or get rid of the (trivial) Python scripts.
Part of #121876.

Coalesce `dep-info`, `dep-info-spaces` and `dep-info-doesnt-run-much` `run-make` tests into `dep-info` rmake.rs
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
This is one of the most ancient tests in the `run-make` directory and its Makefile does some unexpected things, like creating and deleting a `done` directory over and over, sleeping at certain times (this is the [commit](https://github.com/rust-lang/rust/pull/13288/commits/0d9fd8e2a1f8aa43b4cf66272eaa3cf695bbdcd9) that added the `sleep`).
I tried to preserve the intent of the test, which is smoke-testing that `dep-info` works.

Port `run-make/sysroot-crates-are-unstable` to rmake
I already have a more elaborate draft at #126231 that tries to port the underlying Python script to rmake, but there's no need for the removal of Makefiles to be held up on complex tasks like that, so this PR simply takes the trivial Makefile and converts it into a trivial rmake recipe.
Part of #121876.

Add windows-targets crate to std's sysroot
With this PR, when backtrace is used as a crate from crates.io it will (once updated) use the real [windows-targets](https://crates.io/crates/windows-targets) crate. But when used from std it'll use std's replacement version.
This allows sharing our customized `windows_tagets::link!` macro between std proper and the backtrace crate when used as part of std, ensuring a consistent linking story. This will be especially important once we move to using [`raw-dylib`](https://doc.rust-lang.org/reference/items/external-blocks.html#dylib-versus-raw-dylib) by default.
