9ee0192095 Add prefix to every line of -Zhir-stats output. 
This is based on `-Zprint-type-sizes` which does the same thing. It
makes the output provenance clearer, and helps with post-processing.
E.g. if you have `-Zhir-stats` output from numerous compiler invocations
you can now easily extract the pre-expansion stats separately from the
post-expansion stats.

ddee45e1d7 Support #[unix_sigpipe = "inherit|sig_dfl|sig_ign"] on fn main() 
This makes it possible to instruct libstd to never touch the signal
handler for `SIGPIPE`, which makes programs pipeable by default (e.g.
with `./your-program | head -n 1`) without `ErrorKind::BrokenPipe`
errors.

91f128baf7 Auto merge of #92845 - Amanieu:std_personality, r=Mark-Simulacrum 
Move EH personality functions to std

These were previously in the panic_unwind crate with dummy stubs in the
panic_abort crate. However it turns out that this is insufficient: we
still need a proper personality function even with -C panic=abort to
handle the following cases:

1) `extern "C-unwind"` still needs to catch foreign exceptions with -C
panic=abort to turn them into aborts. This requires landing pads and a
personality function.

2) ARM EHABI uses the personality function when creating backtraces.
The dummy personality function in panic_abort was causing backtrace
generation to get stuck in a loop since the personality function is
responsible for advancing the unwind state to the next frame.

Fixes #41004

1e978a3627 Auto merge of #96946 - WaffleLapkin:ptr_mask, r=scottmcm 
Add pointer masking convenience functions

This PR adds the following public API:
```rust
impl<T: ?Sized> *const T {
    fn mask(self, mask: usize) -> *const T;
}

impl<T: ?Sized> *mut T {
    fn mask(self, mask: usize) -> *const T;
}

// mod intrinsics
fn mask<T>(ptr: *const T, mask: usize) -> *const T
```
This is equivalent to `ptr.map_addr(|a| a & mask)` but also uses a cool llvm intrinsic.

Proposed in https://github.com/rust-lang/rust/pull/95643#issuecomment-1121562352

eaadb8947b Auto merge of #100591 - est31:stabilization_placeholder, r=Mark-Simulacrum 
Require stabilizations to use a placeholder instead of writing out stabilization version

Implements the idea from [this](https://rust-lang.zulipchat.com/#narrow/stream/241545-t-release/topic/libs.20stabilization.20placeholder) zulip stream.

It's a common phenomenon that feature stabilizations don't make it into a particular release, but the version is still inaccurate. Often this is caught in the PR, but it can also require subsequent changes to adjust/correct the version. A list with examples of such PRs is given in #100577, but it's far from complete.

This PR requires stabilization PRs to use the placeholder `CURRENT_RUSTC_VERSION`, enforced via tidy tooling. The PR also adds a tool that replaces the placeholder with the version number. It can be invoked via `./x.py run src/tools/replace-version-placeholder` and is supposed to be ran upon beta branching as well as version bumping and any backports to the beta branch.  I filed PRs to the dev guide and forge to document these changes in the release and stabilization workflows:

* The [dev guide](https://rustc-dev-guide.rust-lang.org/stabilization_guide.html#determining-the-stabilization-version) PR: https://github.com/rust-lang/rustc-dev-guide/pull/1443
* The [std dev guide](https://std-dev-guide.rust-lang.org/) PR: https://github.com/rust-lang/std-dev-guide/pull/43
* The [forge](https://github.com/rust-lang/rust-forge) PR: https://github.com/rust-lang/rust-forge/pull/643

Alternative to #100577 which added checking.

1dd47b04c0 Set DebuginfoKind::Pdb in msvc_base 
This PDB setting was added to `windows_msvc_base` in
https://github.com/rust-lang/rust/pull/98051. It's also needed for the
UEFI targets, and since `uefi_msvc_base` and `windows_msvc_base` are the
only things that inherit from `msvc_base`, just move the PDB setting up
to `mscv_base` to cover both.

Fixes https://github.com/rust-lang/rust/issues/101071
