Updating issue templates to avoid @rustbot triggers
This adds a space between the ``@`` and the name *rustbot*. This should now surely fix it. If not, I'm giving up.

Target directory cleanup
changelog: none
* .cargo/config now has `target-dir` specified so that it is inherited by child projects. The target directory needs to be shared with clippy_dev, but not necessarily at the project root. (cc #7625)
* Uses `std::env::current_exe` (and its parent directories) whenever possible
* `CLIPPY_DRIVER_PATH` and `TARGET_LIBS` are no longer required from rustc bootstrap (but `HOST_LIBS` still is). These can be removed from the rustc side after merging.
* `CLIPPY_DOGFOOD` and the separate target directory are removed. This was originally added to mitigate #7343.

This lint is full of weird nuances and this is basically a re-write to tighten up the logic.
Introduce NullOp::AlignOf
This PR introduces `Rvalue::NullaryOp(NullOp::AlignOf, ty)`, which will be lowered from `align_of`, similar to `size_of` lowering to `Rvalue::NullaryOp(NullOp::SizeOf, ty)`.
The changes are originally part of #88700 but since it's not dependent on other changes and could have performance impact on its own, it's separated into its own PR.
Encode spans relative to the enclosing item
The aim of this PR is to avoid recomputing queries when code is moved without modification.
MCP at https://github.com/rust-lang/compiler-team/issues/443
This is achieved by :
1. storing the HIR owner LocalDefId information inside the span;
2. encoding and decoding spans relative to the enclosing item in the incremental on-disk cache;
3. marking a dependency to the `source_span(LocalDefId)` query when we translate a span from the short (`Span`) representation to its explicit (`SpanData`) representation.
Since all client code uses `Span`, step 3 ensures that all manipulations
of span byte positions actually create the dependency edge between
the caller and the `source_span(LocalDefId)`.
This query return the actual absolute span of the parent item.
As a consequence, any source code motion that changes the absolute byte position of a node will either:
- modify the distance to the parent's beginning, so change the relative span's hash;
- dirty `source_span`, and trigger the incremental recomputation of all code that
depends on the span's absolute byte position.
With this scheme, I believe the dependency tracking to be accurate.
For the moment, the spans are marked during lowering.
I'd rather do this during def-collection,
but the AST MutVisitor is not practical enough just yet.
The only difference is that we attach macro-expanded spans
to their expansion point instead of the macro itself.
Fix result order for `manual_split_once` when `rsplitn` is used

rustc: use more correct span data in for loop desugaring
Fixes#82462
Before:
help: consider adding semicolon after the expression so its temporaries are dropped sooner, before the local variables declared by the block are dropped
|
LL | for x in DroppingSlice(&*v).iter(); {
| +
After:
help: consider adding semicolon after the expression so its temporaries are dropped sooner, before the local variables declared by the block are dropped
|
LL | };
| +
This seems like a reasonable fix: since the desugared "expr_drop_temps_mut" contains the entire desugared loop construct, its span should contain the entire loop construct as well.
Backport remerge
This is to keep the backported commit in the repository before force pushing the new beta branch.

Allow giving reasons for `disallowed_methods`
Fixes#7609.
This permits writing the config for `disallowed-methods` as either a list of strings (like before) or a list of tables, where each table gives the path to the disallowed method and an optional reason for why the method is disallowed.
