And likewise for the `Const::val` method.
Because its type is called `ConstKind`. Also `val` is a confusing name
because `ConstKind` is an enum with seven variants, one of which is
called `Value`. Also, this gives consistency with `TyS` and `PredicateS`
which have `kind` fields.
The commit also renames a few `Const` variables from `val` to `c`, to
avoid confusion with the `ConstKind::Value` variant.
Fix error message for `download-ci-llvm`
The error message when `download-ci-llvm` fails includes too many newlines right now:
```
curl: (22) The requested URL returned error: 404
error: failed to download llvm from ci
help: old builds get deleted after a certain time
help: if trying to compile an old commit of rustc, disable `download-ci-llvm` in config.toml:

download-ci-llvm = false

```
This PR fixes the message to include the right amount of newlines:

Remove unnecessary `to_string` and `String::new`
73fa217bc1 changed the type of the `suggestion` argument to `impl ToString`. This patch removes unnecessary `to_string` and `String::new`.

Make `type_changing_struct_update` no longer an incomplete feature
After #97705, I don't see what would make it incomplete anymore. `check_expr_struct_fields` seems to now implement the RFC to the letter.

interpret: unify offset_from check with offset check
`offset` does the check with a single `check_ptr_access` call while `offset_from` used two calls. Make them both just one one call.
I originally intended to actually factor this into a common function, but I am no longer sure if that makes a lot of sense... the two functions start with pretty different precondition (e.g. `offset` *knows* that the 2nd pointer has the same provenance).
I also reworded the UB messages a little. Saying it "cannot" do something is not how we usually phrase UB (as far as I know). Instead it's not *allowed* to do that.

Use safer `strip=symbols`-flag for dylibs on macOS
Closes#93988
To safely strip dylibs on macOS, the `-x` flag is needed per the manpage (see the discussion here: https://github.com/rust-lang/rust/issues/93988#issuecomment-1042574854).
Thus, when the current `crate_type` is producing a dylib (I assume this is the case for proc macros) use the `-x` flag instead of bare `strip` for `strip=symbols`.
Tidy up miscellaneous bounds suggestions
Just some small fixes to suggestions
- Generalizes `Ty::is_suggestable` into a `TypeVisitor`, so that it can be called on things other than `Ty`
- Makes `impl Trait` in arg position no longer suggestible (generalizing the fix in #97640)
- Fixes `impl Trait` not being replaced with fresh type param when it's deeply nested in function signature (fixes#97760)
- Fixes some poor handling of `where` clauses with no predicates (also #97760)
- Uses `InferCtxt::resolve_numeric_literals_with_default` so we suggest `i32` instead of `{integer}` (fixes#97677)
Sorry there aren't many tests the fixes. Most of them would just be duplicates of other tests with empty `where` clauses or `impl Trait` in arg position instead of generic params. Let me know if you'd want more test coverage.
