Extend the `SizeSkeleton` evaluator to shortcut zero-sized arrays, thus considering `[T; 0]` to have a compile-time fixed-size of 0. The existing evaluator already deals with generic arrays under the feature-guard `transmute_const_generics`. However, it merely allows comparing fixed-size types with fixed-size types, and generic types with generic types. For generic types, it merely compares whether their arguments match (ordering them first). Even if their exact sizes are not known at compile time, it can ensure that they will eventually be the same. This patch extends this by shortcutting the size-evaluation of zero sized arrays and thus allowing size comparisons of `()` with `[T; 0]`, where one contains generics and the other does not. This code is guarded by `transmute_const_generics` (rust-lang#109929), even though it is unclear whether it should be. However, this assumes that a separate stabilization PR is required to move this out of the feature guard. Initially reported in rust-lang#98104.

…d increase contrast by setting text color to black
On modern Linux with Intel AMX and 1KiB matrices, Arm SVE with potentially 2KiB vectors, and RISCV Vectors with up to 16KiB vectors, we must handle dynamic signal stack sizes. We can do so unconditionally by using getauxval, but assuming it may return 0 as an answer, thus falling back to the old constant if needed.
…igstksz, r=m-ou-se Dynamically size sigaltstk in std On modern Linux with Intel AMX and 1KiB matrices, Arm SVE with potentially 2KiB vectors, and RISCV Vectors with up to 16KiB vectors, we must handle dynamic signal stack sizes. We can do so unconditionally by using getauxval, but assuming it may return 0 as an answer, thus falling back to the old constant if needed. Fixes rust-lang#107795
…enkov Remove `feed_local_def_id` best reviewed commit by commit Basically I returned `TyCtxtFeed` from `create_def` and then preserved that in the local caches based on rust-lang#121084 r? ```@petrochenkov```

Rust is a proper name: rust → Rust I only went over the library where it might be user-visible -- I noticed this in the `time` docs.
Make `x t miri` respect `MIRI_TEMP` (I don't want to override `TMPDIR`, as that might affect other things) r? `@RalfJung`
…affleLapkin Make not finding core a fatal error Similar to rust-lang#120472, this prevents terminal spam. In particular, it makes the good diagnostic visible when you try to use a target that's not installed.
…ler-errors Cancel parsing ever made during recovery Fixes rust-lang#122112 It would be nice if diagnostics from recovery were automatically cancelled... 🤔
…ld-belongs-to-unix, r=ChrisDenton Fix `tidy --bless` on ̶X̶e̶n̶i̶x̶ Windows As reported in rust-lang#120628 (comment) the requested `tidy --bless` implementation didn't take into account the fact that earlier the linting code canonicalized things to use the OS path separator. This makes it so that the path separator is always rewritten back as '/', which should fix the variance there. r? `@ChrisDenton`
