This commit adds a new lint named `filter_map_identity`. This lint is
the same as `flat_map_identity` except that it checks for `filter_map`.

`@rustbot` modify labels: rollup
Do not check if clippy version matches rustc version when runnning tests inside the rustc repo.
This makes sure that upstream rustc maintainers do not have to deal with our test failing/mismatching versions
when the rustc version bump is happening.
cc #6683
Make rustdoc respect `--error-format short` in doctests
Note that this will not work with `cargo test`, only with `rustdoc --test`, I'll have to modify `cargo` as well.
Fix#81662.
`@rustbot` label +T-rustdoc +A-doctests
Avoid a hir access inside get_static
Together with #81056 this ensures that the codegen unit DepNode doesn't have a direct dependency on any part of the hir.
BTreeMap: make Ord bound explicit, compile-test its absence
Most `BTreeMap` and `BTreeSet` members are subject to an `Ord` bound but a fair number of methods are not. To better convey and perhaps later tune the `Ord` bound, make it stand out in individual `where` clauses, instead of once far away at the beginning of an `impl` block. This PR does not introduce or remove any bounds.
Also adds compilation test cases checking that the bound doesn't creep in unintended on the historically unbounded methods.
Fix rustc sysroot in systems using CAS
Change filesearch::get_or_default_sysroot() to check if sysroot is found using env::args().next() if rustc in argv[0] is a symlink; otherwise, or if it is not found, use env::current_exe() to imply sysroot. This makes the rustc binary able to locate Rust libraries in systems using content-addressable storage (CAS).
An ICE happened when certain code is compiled in incremental compilation
mode and there are two `Ident`s that have the same `StableHash` value
but are considered different by `Eq` and `Hash`.
The `Ident` issue is now fixed.
Encode MIR metadata by iterating on DefId instead of traversing the HIR tree
Split out of https://github.com/rust-lang/rust/pull/80347.
This part only traverses `mir_keys` and encodes MIR according to the def kind.

Use absolute path to Rust repo in ra_setup
This will convert the path to the Rust repo to an absolute path. This is
important for the clippy_lints/Cargo.toml file. Otherwise if a relative
path is passed, rst-analyzer won't find the Rust repo, because it starts
the relative path search from the clippy_lints dir, not the
rust-clippy dir where the ra_setup command was run from.
