Such implementations are usually mistakes and are not used in the compiler or standard library (after this commit) so forbid them with `min_specialization`.

Add an obligation cause for these error so that the error points to the implementations that caused the error.

We really shouldn't be naming functions `fn check_*` unless they're doing *typechecking*. It's especially misleading when we're doing this inside of HIR typeck.

Add GNU Property Note Fix rust-lang#103001 Generates the missing property note: ``` Displaying notes found in: .note.gnu.property Owner Data size Description GNU 0x00000010 NT_GNU_PROPERTY_TYPE_0 Properties: x86 feature: IBT ```

… r=cjgillot Tweak borrow suggestion span Avoids a `span_to_snippet` call when we don't need to surround the expression in parentheses. The fact that the suggestion was using the whole span of the expression rather than just appending a `&` was prevented me from using `// run-rustfix` in another PR (rust-lang#110432 (comment)). Also some drive-by renames of functions that have been annoying me for a bit.

…stebank tweak "make mut" spans when assigning to locals Work towards fixing rust-lang#106857 This PR just cleans up a lot of spans which is helpful before properly fixing the issues. Best reviewed commit-by-commit. r? `@estebank`

Implement builtin # syntax and use it for offset_of!(...) Add `builtin #` syntax to the parser, as well as a generic infrastructure to support both item and expression position builtin syntaxes. The PR also uses this infrastructure for the implementation of the `offset_of!` macro, added by rust-lang#106934. cc `@petrochenkov` `@DrMeepster` cc rust-lang#110680 `builtin #` tracking issue cc rust-lang#106655 `offset_of!` tracking issue

…s, r=compiler-errors Min specialization improvements - Don't allow specialization impls with no items, such implementations are probably not correct and only occur as mistakes in the compiler and standard library - Fix a missing normalization call - Adds spans for lifetime errors from overly general specializations Closes rust-lang#79457 Closes rust-lang#109815
