Add inline attribute to generated delegation function if needed
This PR adds a functionality to add #[inline(always)] attribute to generated functions from delegation, if some #[inline(..)] attribute is already specified on the delegation then we do nothing. This PR is a part of the delegation feature rust-lang/rust#118212 and addresses `Add implicit #[inline] unless specified otherwise` item.

bootstrap: Use a `CompiletestMode` enum instead of bare strings
This gives better static checking when dealing with compiletest modes in bootstrap, especially for those modes that overlap with the name of a test suite directory.

Retire `opt_str2` from compiletest cli parsing
We have `Option<..>`, we don't need to invent "(none)" as option-at-home.
- More specifically, when some test suite expect certain values to be present, they should `.expect(..)` the value, and not potentially receive some "(none)" in some cases.

lint: emit proper diagnostic for unsafe binders in improper_ctypes instead of ICE
Fixesrust-lang/rust#149719
This PR replaces the `todo!("FIXME(unsafe_binder)")` branch in the `improper_ctypes` lint with a proper diagnostic.
Previously, using an unsafe binder inside an extern `"C"` block caused an internal compiler error.
This fix now ensures that the compiler now emits a clear and stable error message explaining that types containing unsafe binders are not yet supported in FFI.
A new UI test `(unsafe-binder-basic.rs)` is included to ensure this behavior remains stable and prevent regressions.
Emit `check-cfg` lints during attribute parsing rather than evaluation
The goal of this PR is to make the `eval_config_entry` not have any side effects, by moving the check-cfg lints to the attribute parsing. This also helps ensure we do emit the lint in situations where the attribute happens to be parsed, but never evaluated.

std: Use more `unix.rs` code on WASI targets
This commit is a large change to the implementation of filesystem and
other system-related operations on WASI targets. Previously the standard
library explicitly used the `wasi` crate at the 0.11.x version track
which means that it used WASIp1 APIs directly. This meant that `std` was
hard-coded to use WASIp1 syscalls and there was no separate
implementation for the WASIp{2,3} targets, for example. The high-level
goal of this commit is to decouple this interaction and avoid the use of
the `wasi` crate on the WASIp2 target.
Historically when WASIp1 was originally added to Rust the wasi-libc
library was in a much different position than it is today. Nowadays Rust
already depends on wasi-libc on WASI targets for things like memory
allocation and environment variable management. As a libc library it
also has all the functions necessary to implement all filesystem
operations Rust wants. Recently wasi-libc additionally was updated to
use WASIp2 APIs directly on the `wasm32-wasip2` target instead of using
`wasm32-wasip1` APIs. This commit is leveraging this work by enabling
Rust to completely sever the dependence on WASIp1 APIs when compiling
for `wasm32-wasip2`. This is also intended to make it easier to migrate
to `wasm32-wasip3` internally in the future where now only libc need be
updated and Rust doesn't need to explicitly change as well.
The overall premise of this commit is that there's no need for
WASI-specific implementation modules throughout the standard library.
Instead the libc-style bindings already implemented for Unix-like
targets are sufficient. This means that Rust will now be using
libc-style interfaces to interact with the filesystem, for example, and
wasi-libc is the one responsible for translating these POSIX-ish
functions into WASIp{1,2} calls.
Concrete changes here are:
* `std` for `wasm32-wasip2` no longer depends on `wasi 0.11.x`
* The implementation of `std::os::wasi::fs`, which was previously
unstable and still is, now has portions gated to only work on the
WASIp1 target which use the `wasi` crate directly. Traits have been
trimmed down in some cases, updated in others, or now present a
different API on WASIp1 and WASIp2. It's expected this'll get further
cleanup in the future.
* The `std::sys::fd::wasi` module is deleted and `unix` is used instead.
* The `std::sys::fs::wasi` module is deleted and `unix` is used instead.
* The `std::sys::io::io_slice::wasi` module is deleted and `unix` is used
instead.
* The `std::sys::pal::{wasip1,wasip2}` modules are now merged together
as their difference is much smaller than before.
* The `std::sys::pal::wasi::time` is deleted and the `unix` variant is
used directly instead.
* The `std::sys::stdio::wasip{1,2}` modules are deleted and the `unix`
variant is used instead.
* The `std::sys:🧵:wasip{1,2}` modules are deleted and the `unix`
variant is used instead.
Overall Rust's libstd is effectively more tightly bound to libc when
compiled to WASI targets. This is intended to mirror how it's expected
all other languages will also bind to WASI. This additionally has the
nice goal of drastically reducing the WASI-specific maintenance burden
in libstd (in theory) and the only real changes required here are extra
definitions being added to `libc` (done in separate PRs). This might be
required for more symbols in the future but for now everything should be
mostly complete.
Move the libgccjit.so file in a target directory
Since GCC is not multi-target, we need multiple libgccjit.so. Our solution to have a directory per target so that we can have multiple libgccjit.so.

Subtree sync for rustc_codegen_cranelift
The main highlights this time are a Cranelift update and adding actual support for `-Cdebuginfo=line-tables-only` rather than treating it the same as `-Cdebuginfo=full`.

This derive was an artifact of test-only method `Cache::all` wanting to
automatically sort its output to hide HashMap iteration order.
We can achieve an equivalent result by requiring the caller to provide a
projection function that returns results that _are_ sortable.
contracts: clean up feature flag warning duplicated across tests
There is no need for every contracts test to assert the same warning for using the `contracts` feature flag, as such use `#![expect(incomplete_features)]` in the tests, and add one test to specifically check for the warning.
Making this change has been discussed in the comments of rust-lang/rust#149722.

contracts: fix lowering final declaration without trailing semicolon
Lowering for contract delcarations introduced in rust-lang/rust#144444 incorrectly handled the final declaration statement when it didn't end in a semicolon. This change fixes the issue.

Move ambient gdb discovery from compiletest to bootstrap
- Follow-up to https://github.com/rust-lang/rust/pull/148099
---
This code takes the compiletest code for discovering an “ambient” `gdb` in the user's path, and moves it to bootstrap.
One of the eventual goals is to allow compiletest to assume that if it has been asked to run the debuginfo-gdb suite, then it *must* have been passed an explicit `--gdb`, though we aren't quite there yet.

Add `ilog10` result range hints
This PR adds hints that the return value of `T::ilog10` will never exceed `T::MAX.ilog10()`.
This works because `ilog10` is a monotonically nondecreasing function, the maximum return value is reached at the max input value.
Improve error message for std integer clamp() if min > max
For rust-lang/rust#142309: change the error message for `Ord::clamp()` for std integer types if min > max to be more useful.
Message is now `min > max. min = {min:?}, max = {max:?}`
Also add `#[track_caller]` to `clamp()`
