Use `create_snapshot_for_diagnostic` instead of `clone` for `Parser`

Use [`create_snapshot_for_diagnostic`](cd11905716/compiler/rustc_parse/src/parser/diagnostics.rs (L214-L223)) I implemented in https://github.com/rust-lang/rust/pull/94731 instead of `clone` to avoid duplicate unclosed delims errors being emitted when the `Parser` is dropped. I missed this one in #95068.

Rollup merge of #97991 - davidkna:fix-macos-strip, r=joshtriplett 
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`.

fn main() -> Result<(), Error> {

37a42258ff Auto merge of #97778 - compiler-errors:misc-diagnostics-tidy, r=cjgillot 
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.

99930ac7f8 Auto merge of #95880 - cjgillot:def-ident-span, r=petrochenkov 
Handle `def_ident_span` like `def_span`.

`def_ident_span` had an ad-hoc status in the compiler.

This PR refactors it to be a first-class citizen like `def_span`:
- it gets encoded in the main metadata loop, instead of the visitor;
- its implementation is updated to mirror the one of `def_span`.

We do not remove the `Option` in the return type, since some items do not have an ident, AnonConsts for instance.

Rollup merge of #97969 - inglorion:prelinkpasses, r=nikic 
Make -Cpasses= only apply to pre-link optimization

This change causes passes specified in -Cpasses= to be applied
only during pre-link optimization, not during LTO. This avoids
such passes running multiple times, which they may not be
designed for.
