This is a basic copy-paste-modify from the existing
x86_64-apple-darwin target.

This adds a dedicated branch for perf to use for CI, intended to allow perf to
enqueue builds without needing to use bors. bors is great, but bors requires an
open PR to work, and we want to invoke perf on closed PRs sometimes (in
particular, rollups).

Add a FIXME to build scripts in profiler_builtins

Address rust-lang#71341.

Change the logic such that linking from a public to a private item always
triggers intra_doc_link_resolution_failure. Previously, the warning was
not emitted when --document-private-items is passed.

Also don't rely anymore on the item's visibility, which would falsely trigger
the lint now that the check for --document-private-items is gone.

…links

The additional note helps explaining why the lint was triggered and that
--document-private-items directly influences the link resolution.

rustdoc: Always warn when linking from public to private items

Change the logic such that linking from a public to a private item always triggers `intra_doc_link_resolution_failure`.
Previously, the warning was not emitted when `--document-private-items` is passed.

This came up during the discussion in rust-lang#74147 (comment).

Guard against non-monomorphized type_id intrinsic call

This PR checks whether the type is sufficient monomorphized when calling type_id or type_name intrinsics. If the type is not sufficiently monomorphized, e.g. used in a pattern, the code will be rejected.

Fixes rust-lang#73976

rustc_target: Add a target spec option for disabling `--eh-frame-hdr`

Disable `--eh-frame-hdr` for targets that use an `ld`-like linker, but don't support that option.
Do it through a target spec option rather than through hard-coding in `linker.rs`.
The option is still enabled by default though.

build: Remove unnecessary `cargo:rerun-if-env-changed` annotations

... and a couple of related cleanups.

rustc and cargo now track the majority of env var dependencies automatically (rust-lang/cargo#8421), so the annotations are no longer necessary.
