in which we decline to suggest the anonymous lifetime in declarations
The elided-lifetimes-in-path lint (part of our suite of Rust 2018 idiom lints which we are hoping to promote to Warn status) was firing with an illegal suggestion to write an anonymous lifetime in a
struct/item declaration (where we don't allow it). The linting code was already deciding whether to act on the basis of a `ParamMode` enum, indicating whether the present path-segment was part of an
expression, or anywhere else. The present case seemed to be part of the "anywhere else", and yet meriting different rules as far as the lint was concerned, so it seemed expedient to introduce a new enum member. We yank out `TyKind::Path` arm into its own method so that we can call it with our new `ParamMode` specifically when lowering struct fields—one would have hoped to think of something more elegant than this, but it definitely beats changing the signature of `lower_ty` to take a `ParamMode`!
Resolves#61124.

The elided-lifetimes-in-path lint (part of our suite of Rust 2018

with an illegal suggestion to write an anonymous lifetime in a
struct/item declaration (where we don't allow it). The linting code
was already deciding whether to act on the basis of a `ParamMode`
enum, indicating whether the present path-segment was part of an

the "anywhere else", and yet meriting different rules as far as the
lint was concerned, so it seemed expedient to introduce a new enum
member. We yank out a `TyKind::Path` arm into its own method so that
we can call it with our new `ParamMode` specifically when lowering
struct fields. (The alternative strategy of changing the signature of
`lower_ty` to take a `ParamMode` would be inelegant given that most of
the `TyKind` match arm bodies therein don't concern themselves with
`ParamMode`.)
Resolves#61124.
This commit extends the work in #61698 to get the `DefId` of const
parameters from block that resolve to a const parameter (as well as
const parameters directly, as it was previously).
Bootstrap cleanup
Each commit is (mostly) standalone and probably best reviewed as such. Nothing too major just some drive-by nits as I was looking through the code.

LLVM appears to prefer (spend less time optimizing) long if chains if
it receives them in approzimately source order.
This fixes a ~10% regression for optimized builds of the encoding benchmark
on perf.rlo due to the changes to decision tree construction.
ci: Enable toolstate tracking on Azure
Currently just run it through its paces but don't actually push to
official locations. Instead let's just push to a separate fork (mine) as
well as open issues in a separate fork (mine). Make sure that people
aren't pinged for these issues as well!
This should hopefully ensure that everything is working on Azure and
give us a chance to work through any issues that come up.
Fixes https://github.com/rust-lang/rust/issues/61790
Fixes https://github.com/rust-lang/rust/issues/61371
Removing the tool argument in the previous commit means it's no longer
restricted to just bootstrap tools despite being written as such.
Inlining it prevents accidental use.

std: Remove internal definitions of `cfg_if!` macro
This is duplicated in a few locations throughout the sysroot to work
around issues with not exporting a macro in libstd but still wanting it
available to sysroot crates to define blocks. Nowadays though we can
simply depend on the `cfg-if` crate on crates.io, allowing us to use it
from there!
It is unclear if accessing an integer after `drop_in_place` has been
called on it is undefined behaviour or not, as demonstrated by the
discussion in
https://github.com/rust-lang/rust/pull/60766#pullrequestreview-243414222.
Avoid these uncertainties by using String which frees memory in its
`drop_in_place` to make sure this is undefined behaviour. The message in
the docs should be to watch out and not access the data after that, not
discussing when one maybe could get away with it O:-).
