69f26b7761 Use fixed type for CodegenResults
This also moves the -Zno-link implementation to rustc_interface

f141acf067 Move finalize_session_directory call out of cg_llvm
This causes it to be called even when passing `-Zno-link`, when linking
fails or when neither `--emit link` nor `--emit metadata` is used.

Attach tokens to ast::Stmt
We currently only attach tokens when parsing a `:stmt` matcher for a
`macro_rules!` macro. Proc-macro attributes on statements are still
unstable, and need additional work.

Attach TokenStream to ast::Block
A `Block` does not have outer attributes, so we only capture tokens when
parsing a `macro_rules!` matcher

af3c6e733a Auto merge of #73996 - da-x:short-unique-paths, r=petrochenkov
diagnostics: shorten paths of unique symbols

This is a step towards implementing a fix for #50310, and continuation of the discussion in [Pre-RFC: Nicer Types In Diagnostics - compiler - Rust Internals](https://internals.rust-lang.org/t/pre-rfc-nicer-types-in-diagnostics/11139). Impressed upon me from previous discussion in #21934 that an RFC for this is not needed, and I should just come up with code.

The recent improvements to `use` suggestions that I've contributed have given rise to this implementation. Contrary to previous suggestions, it's rather simple logic, and I believe it only reduces the amount of cognitive load that a developer would need when reading type errors.

-----

If a symbol name can only be imported from one place, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path to the last component.

This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable from anywhere.

07e7823c01 pretty: trim paths of unique symbols
If a symbol name can only be imported from one place for a type, and
as long as it was not glob-imported anywhere in the current crate, we
can trim its printed path and print only the name.

This has wide implications on error messages with types, for example,
shortening `std::vec::Vec` to just `Vec`, as long as there is no other
`Vec` importable anywhere.

This adds a new '-Z trim-diagnostic-paths=false' option to control this
feature.

On the good path, with no diagnosis printed, we should try to avoid
issuing this query, so we need to prevent trimmed_def_paths query on
several cases.

This change also relies on a previous commit that differentiates
between `Debug` and `Display` on various rustc types, where the latter
is trimmed and presented to the user and the former is not.

da897dfb6d Auto merge of #76216 - marmeladema:use-once-cell-from-std, r=matklad
compiler: use `OnceCell` from std

Fixes #76192

The only remaining direct use of `lazy_static` crate is in `src/bootstrap`  but I am not sure how I can remove that dependency for now.

Add -Z proc-macro-backtrace to allow showing proc-macro panics
Fixes #75050

Previously, we would unconditionally suppress the panic hook during
proc-macro execution. This commit adds a new flag
-Z proc-macro-backtrace, which allows running the panic hook for
easier debugging.
