When suggesting to import an item, also suggest changing the path if appropriate
When we don't find an item we search all of them for an appropriate
import and suggest `use`ing it. This is sometimes done for expressions
that have paths with more than one segment. We now also suggest changing
that path to work with the `use`.
Fix#95413
Easier readability for `needless_late_init` message
Closes#8530
Updated the lint to use a `MultiSpan`, showing where the `let` statement was first used and where the initialisation statement was done, as in the format described, for easier readability.
Was wondering why, when pushing the span label for the initialisation statement, that sometimes the prior statement above the initialisation statement gets pulled into the output as well - any insight is appreciated!

changelog: [`needless_late_init`]: Now shows the `let` statement where it was first initialized
The comment on this function explains that it's a specialized version of
`maybe_whole_expr`. But `maybe_whole_expr` doesn't do anything with
`NtIdent`, so `is_whole_expr` also doesn't need to.
Move only_used_in_recursion to nursery
r? `@llogiq`
I still think this is the right thing to do for this lint. See: #8782
I want to get this merged before the sync on Thursday, because I want to backport this and the last fix#8691 to beta.
changelog: Move [`only_used_in_recursion`] to nursery
Cleanup `DebuggerVisualizerFile` type and other minor cleanup of queries.
Merge the queries for debugger visualizers into a single query.
Revert move of `resolve_path` to `rustc_builtin_macros`. Update dependencies in Cargo.toml for `rustc_passes`.
Respond to PR comments. Load visualizer files into opaque bytes `Vec<u8>`. Debugger visualizers for dynamically linked crates should not be embedded in the current crate.
Update the unstable book with the new feature. Add the tracking issue for the debugger_visualizer feature.
Respond to PR comments and minor cleanups.

Use reverse postorder in `non_ssa_locals`
The reverse postorder, unlike preorder, is now cached inside the MIR
body. Code generation uses reverse postorder anyway, so it might be
a small perf improvement to use it here as well.
[FP] identity_op in front of if
fix#8724
changelog: FP: [`identity_op`]: is now allowed in front of if statements, blocks and other expressions where the suggestion would be invalid.
Resolved simular problems with blocks, mathces, and loops.
identity_op always does NOT suggest reducing `0 + if b { 1 } else { 2 } + 3` into `if b { 1 } else { 2 } + 3` even in the case that the expression is in `f(expr)` or `let x = expr;` for now.

Mitigate impact of subtle invalid call suggestion logic
There's some subtle interaction between inferred expressions being
passed as an argument to fn calls with fewer than expected arguments. To
avoid the ICE, I'm changing indexing operations with `.get(idx)`, but
the underlying logic still needs to be audited as it was written with
the assumption that `final_arg_types` and `provided_args` have the right
length.
Address #96638.
Update `RValue::Discriminant` documentation
`RValue::Discriminant` returns zero for types without discriminant.
This guarantee is already documented for `discriminant_value`
intrinsics which is implemented in terms of `RValue::Discriminant`.
Use source callsite in check_argument_types suggestion
This makes the "remove extra arguement" suggestion valid when the function argument is a macro.
Additionally, this may fix#96225, but the only way I can reproduce that issue is using the playground, so we will need to wait until after this is merged to ensure it's fixed.
Refactor the WriteBackendMethods and ExtraBackendMethods traits
The new interface is slightly less confusing and is easier to implement for non-LLVM backends.
When we don't find an item we search all of them for an appropriate
import and suggest `use`ing it. This is sometimes done for expressions
that have paths with more than one segment. We now also suggest changing
that path to work with the `use`.
