Remove hir::CrateItem.

The crate span is exactly the crate module's inner span. There is no need to store it twice.

rustdoc: Only look at blanket impls in `get_blanket_impls`

The idea here is that all the work in 16156fb278/compiler/rustc_middle/src/ty/trait_def.rs (L172-L186) doesn't matter for `get_blanket_impls` - Rustdoc will already pick up on those blocks when it documents the item.

Run LLVM coverage instrumentation passes before optimization passes

This matches the behavior of Clang and allows us to remove several
hacks which were needed to ensure functions weren't optimized away
before reaching the instrumentation pass.

a0e229abad Auto merge of #83649 - bjorn3:dedup_providers, r=petrochenkov 
Don't duplicate the extern providers once for each crate

This should give a small perf improvement for small crates by avoiding a memcpy of a pretty big struct for each loaded crate. In addition would be useful for replacing the sequential `CrateNum` everywhere with the hash based `StableCrateId` introduced in #81635, which would allow avoiding remapping of `CrateNum`'s when loading crate metadata. While this PR is not strictly needed for that, it is necessary to prevent a performance loss due to it.

I think this duplication was done in https://github.com/rust-lang/rust/pull/40008 (which introduced the query system) to make it possible to compile multiple crates in a single session in the future. I think this is unlikely to be implemented any time soon. In addition this PR can easily be reverted if necessary to implement this.

0195f8d375 Hide unnecessary reference to trait 
When the problem for a method not being found in its receiver is due to
arbitrary self-types, we don't want to mention importing or implementing
the trait, instead we suggest wrapping.

Remove (lots of) dead code

Builds on
- [ ] https://github.com/rust-lang/rust/pull/83161
- [x] https://github.com/rust-lang/rust/pull/83230
- [x] https://github.com/rust-lang/rust/pull/83197.

Found with https://github.com/est31/warnalyzer.
See https://github.com/rust-lang/rust/pull/77739 for a similar change in the past.

Dubious changes:
- Maybe some of the dead code in rustc_data_structures should be kept, in case someone wants to use it in the future?

TODO:
- [ ] check if any of the comments on the deleted code should be kept.
- [x] update the compiler documentation; right now it fails to build
- [x] finish moving `cfg(test)` changes into https://github.com/rust-lang/rust/pull/83197

There isn't currently a good reviewer for these, and I don't want to
remove things that will just be added again. I plan to make a separate
PR for these changes so the rest of the cleanup can land.
