On ELF, the text section is opened with ".text", on MachO with
".section __TEXT,__text".

Previously, on ELF this test was actually matching a GNU note
section, which is no longer emitted on Solaris starting with
LLVM 18.

Fixes rust-lang#120105.

Remove duplicate dependencies for rustc

Removed several duplicates for rustc: rust-lang#75704

Several duplicates still exist, but an external library would have to be updated first.

These are the duplicate dependencies still outstanding:
```
annotate-snippets v0.9.1
annotate-snippets v0.10.1

bitflags v1.3.2
bitflags v2.4.1

cargo_metadata v0.15.4
cargo_metadata v0.18.0

darling v0.14.4
darling v0.20.3

darling_core v0.14.4
darling_core v0.20.3

darling_macro v0.14.4
darling_macro v0.20.3

regex-automata v0.1.10
regex-automata v0.2.0
regex-automata v0.4.3

regex-syntax v0.6.29
regex-syntax v0.7.2
regex-syntax v0.8.2

self_cell v0.10.3
self_cell v1.0.2

syn v1.0.109
syn v2.0.32

toml v0.5.11
toml v0.7.5
```

It should not be hard to consolidate these remaining duplicate dependencies, but it will take time as it would be pull requests for external crates.

coverage: Don't instrument `#[automatically_derived]` functions

This PR makes the coverage instrumentor detect and skip functions that have [`#[automatically_derived]`](https://doc.rust-lang.org/reference/attributes/derive.html#the-automatically_derived-attribute) on their enclosing impl block.

Most notably, this means that methods generated by built-in derives (e.g. `Clone`, `Debug`, `PartialEq`) are now ignored by coverage instrumentation, and won't appear as executed or not-executed in coverage reports.

This is a noticeable change in user-visible behaviour, but overall I think it's a net improvement. For example, we've had a few user requests for this sort of change (e.g. rust-lang#105055, rust-lang#84605 (comment)), and I believe it's the behaviour that most users will expect/prefer by default.

It's possible to imagine situations where users would want to instrument these derived implementations, but I think it's OK to treat that as an opportunity to consider adding more fine-grained option flags to control the details of coverage instrumentation, while leaving this new behaviour as the default.

(Also note that while `-Cinstrument-coverage` is a stable feature, the exact details of coverage instrumentation are allowed to change. So we *can* make this change; the main question is whether we *should*.)

Fixes rust-lang#105055.

Bump some deps with syn 1.0 dependencies

cc rust-lang#109302

`cargo update`ing `unic-langid` and `object` removes two dependencies on Syn 1.0.

Update some deps with `bitflags` v1 dependencies

This only leaves `pulldown-cmark` (which has updated to bitflags v2 in Git) and `rustc_apfloat` (PR opened previously at rust-lang/rustc_apfloat#12)

Use `Self` in `NonZero*` implementations.

This slightly reduces the size of the eventual diff when making these generic, since this can be merged independently.
