allow specifying attributes for tool lints
Needed for clippy to fix `unused_doc_comments` warnings that will be exposed by #57882 (and thus unblock it).
Have all methods of Filter and FilterMap use internal iteration
This PR changes `Filter::{next, next_back, count}` and `FilterMap::{next, next_back}` to all use internal iteration. The `next` and `next_back` methods are changed to directly forward to `try_for_each` and `try_rfold` respectively, using `Result` as the `Try` type. I think that's okay? Alternatively, I could change their implementations to use `LoopState` instead if there's any benefit in doing so.

Set secure flags when opening a named pipe on Windows
Fixes https://github.com/rust-lang/rust/issues/42036, see also the previous attempt in https://github.com/rust-lang/rust/pull/44556.
Whether this is correct depends on if it is somehow possible to create a symlink to a named pipe, outside the named pipe filesystem (NPFS). But as far as I can tell that should be impossible.
Also fixes that `security_qos_flags(SECURITY_ANONYMOUS)` does not set the `SECURITY_SQOS_PRESENT` flag, and the incorrect documentation about the default value of `security_qos_flags`.
Include bounds from promoted constants in NLL
Previously a promoted function wouldn't have its bound propagated out to
the main function body.
When we visit a promoted, we now type check the MIR of the promoted
and transfer any lifetime constraints to back to the main function's MIR.
Fixes#57170

Before this commit, if you're running x.py directly on a system where
`python` is symlinked to Python 3, then the `python` config option will
default to a Python 3 interpreter. This causes debuginfo tests to fail
with an opaque error message, since they have a hard requirement on
Python 2.
This commit modifies the Python probe behavior to look for python2.7 and
python2 *before* using the interpreter used to execute `x.py`.
Type annotations are shared between the MIR of a function and the
promoted constants for that function, so keep them in the type checker
when we check the promoted MIR.
Remove NodeId from more HIR nodes
The next iteration of HirIdification (#57578).
Removes `NodeId` from:
- [x] `Stmt`
- [x] `Local`
- [x] `Field`
- [x] `AnonConst`
- [x] `TraitItem`
- [x] `ImplItem`
- [x] `TypeBinding`
- [x] `Arg`
- [x] `TraitRef`
- [x] `VisibilityKind`
It will most probably break clippy again; I'd appreciate a **delegate** again if/when it is good to go so I can attach a clippy fix later.

Put Local, Static and Promoted as one Base variant of Place
Related to #52708
The `Place` 2.0 representation use a `Base` variant for `Local`, `Static` and `Promoted` so we start making this change in the current `Place` to make the following steps simpler.
