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.

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.

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.

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.

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
