Only store a LocalDefId in some HIR nodes
Some HIR nodes are guaranteed to be HIR owners: Item, TraitItem, ImplItem, ForeignItem and MacroDef.
As a consequence, we do not need to store the `HirId`'s `local_id`, and we can directly store a `LocalDefId`.
This allows to avoid a bit of the dance with `tcx.hir().local_def_id` and `tcx.hir().local_def_id_to_hir_id` mappings.
update RLS and rustfmt
Fixes#81582 and fixes#81583
r? `@Xanewok`
I was originally surprised by the size of lockfile diff, though after looking at the RLS changes it makes a bit more sense to me now

Rename HIR UnOp variants
This renames the variants in HIR UnOp from
enum UnOp {
UnDeref,
UnNot,
UnNeg,
}
to
enum UnOp {
Deref,
Not,
Neg,
}
Motivations:
- This is more consistent with the rest of the code base where most enum
variants don't have a prefix.
- These variants are never used without the `UnOp` prefix so the extra
`Un` prefix doesn't help with readability. E.g. we don't have any
`UnDeref`s in the code, we only have `UnOp::UnDeref`.
- MIR `UnOp` type variants don't have a prefix so this is more
consistent with MIR types.
- "un" prefix reads like "inverse" or "reverse", so as a beginner in
rustc code base when I see "UnDeref" what comes to my mind is
something like `&*` instead of just `*`.

libtest: allow multiple filters
Libtest ignores any filters after the first. This changes it so that if multiple filters are passed, it will test against all of them.
This also affects compiletest to do the same.
Closes#30422
Refactor `PrimitiveTypeTable` for Clippy
I removed `PrimitiveTypeTable` and added `PrimTy::ALL` and `PrimTy::from_name` in its place. This allows Clippy to use `PrimTy::from_name` for the `builtin_type_shadow` lint, and a `const` list of primitive types is deleted from Clippy code (the goal). All changes should be a little faster, if anything.
tidy: Run tidy style against markdown files.
This adds tidy checks for markdown files. I think it is useful to have some style enforcement (for the same reasons the style is enforced on other files). I think it is worthwhile to avoid `ignore` on rust examples since having broken code in documentation is frustrating. Avoiding trailing whitespace is good because it has semantic meaning in markdown, which I think should be avoided.
Make remote-test-server easier to use with new targets
While testing #81455 I encountered 2 issues with `remote-test-server`:
- It is built with the stage 0 toolchain, which does not support a newly added target.
- It overwrites `LD_LIBRARY_PATH` instead of appending to it, which prevents the use of a custom sysroot for target libraries.

Add lint for `panic!(123)` which is not accepted in Rust 2021.
This extends the `panic_fmt` lint to warn for all cases where the first argument cannot be interpreted as a format string, as will happen in Rust 2021.
It suggests to add `"{}",` to format the message as a string. In the case of `std::panic!()`, it also suggests the recently stabilized
`std::panic::panic_any()` function as an alternative.
It renames the lint to `non_fmt_panic` to match the lint naming guidelines.
This is part of #80162.

Add AArch64 big-endian and ILP32 targets
This PR adds 3 new AArch64 targets:
- `aarch64_be-unknown-linux-gnu`
- `aarch64-unknown-linux-gnu_ilp32`
- `aarch64_be-unknown-linux-gnu_ilp32`
It also fixes some ABI issues on big-endian ARM and AArch64.
Add .editorconfig
This adds a .editorconfig file to rust-lang/rust, matching Clippy's. It's not clear that this will benefit many people, but the cost is low and the rewards are potentially meaningful.
Box the biggest ast::ItemKind variants
This PR is a different approach on https://github.com/rust-lang/rust/pull/81400, aiming to save memory in humongous ASTs.
The three affected item kind enums are:
- `ast::ItemKind` (208 -> 112 bytes)
- `ast::AssocItemKind` (176 -> 72 bytes)
- `ast::ForeignItemKind` (176 -> 72 bytes)
Editorconfig is a lightweight specification that
helps maintaining consistent coding/formatting style
accross editors, especially those editors
that are not explicitly aware of Rust and rustfmt.
