This deduplicates some code between codegen backends and may in the
future allow adding extra metadata that is only known at link time.

On Windows, if creating a temporary directory fails with permission denied then use a retry/backoff loop. This hopefully fixes a recuring error in our CI.

This makes this step take ~25ms on my machine (M3 Max 64GB) for Zed repo instead of ~150ms. Additionally it takes down the time needed for a clean cargo build of ripgrep from ~6.1s to 5.9s.
This change is mostly relevant for crates with multiple large CGUs.

`rustc_span::symbol` defines some things that are re-exported from
`rustc_span`, such as `Symbol` and `sym`. But it doesn't re-export some
closely related things such as `Ident` and `kw`. So you can do `use
rustc_span::{Symbol, sym}` but you have to do `use
rustc_span::symbol::{Ident, kw}`, which is inconsistent for no good
reason.
This commit re-exports `Ident`, `kw`, and `MacroRulesNormalizedIdent`,
and changes many `rustc_span::symbol::` qualifiers in `compiler/` to
`rustc_span::`. This is a 200+ net line of code reduction, mostly
because many files with two `use rustc_span` items can be reduced to
one.

As a side effect this should add raw-dylib support to cg_gcc as the
default ArchiveBuilderBuilder that is used implements
create_dll_import_lib. I haven't tested if the raw-dylib support
actually works however.

Set "symbol name" in raw-dylib import libraries to the decorated name
`windows-rs` received a bug report that mixing raw-dylib generated and the Windows SDK import libraries was causing linker failures: <https://github.com/microsoft/windows-rs/issues/3285>
The root cause turned out to be #124958, that is we are not including the decorated name in the import library and so the import name type is also not being correctly set.
This change modifies the generation of import libraries to set the "symbol name" to the fully decorated name and correctly marks the import as being data vs function.
Note that this also required some changes to how the symbol is named within Rust: for MSVC we now need to use the decorated name but for MinGW we still need to use partially decorated (or undecorated) name.
Fixes #124958
Passing i686 MSVC and MinGW build: <https://github.com/rust-lang/rust/actions/runs/11000433888?pr=130586>

This makes it much clearer which things are used outside the crate.

Make create_dll_import_lib easier to implement
This will make it easier to implement raw-dylib support in cg_clif and cg_gcc. This PR doesn't yet include an create_dll_import_lib implementation for cg_clif as I need to correctly implement dllimport in cg_clif first before raw-dylib can work at all with cg_clif.
Required for https://github.com/rust-lang/rustc_codegen_cranelift/issues/1345

Create COFF archives for non-LLVM backends
`ar_archive_writer` now supports creating COFF archives, so enable them for the non-LLVM backends when requested.

When an archive fails to build, print the path
Currently the output on failure is as follows:
Compiling block-buffer v0.10.4
Compiling crypto-common v0.1.6
Compiling digest v0.10.7
Compiling sha2 v0.10.8
Compiling xz2 v0.1.7
error: failed to build archive: No such file or directory
error: could not compile `bootstrap` (lib) due to 1 previous error
Change this to print which file is being constructed, to give some hint about what is going on.

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

From LLVM 15.0.0-rc3. This adds support for COFF archives containing
Arm64EC object files and has various fixes for AIX big archive files.

static libraries with ar_archive_writer
Fixes #107495
|
|
This adds a whole bunch of tests checking for any difference with llvm's
archive writer. It also fixes two mistakes in the porting from C++ to
Rust. The first one causes a divergence for Mach-O archives which may or
may not be harmless. The second will definitively cause issues, but only
applies to thin archives, which rustc currently doesn't create.

Also add some `dcx` methods to types that wrap `TyCtxt`, for easier
access.

`x clippy compiler -Aclippy::all -Wclippy::needless_borrow --fix`.
Then I had to remove a few unnecessary parens and muts that were exposed
now.

FIX - StrippingDebugInfoFailed typo
DELETE - unneeded FIXME comment
UPDATE - only declare the error with ExtractBundledLibsError as an enum and use the Diagnostic derive macro
