Remove `match_path` and `match_qpath`
The only remaining usage is the `author` lint, so the functions are left in for now. The test result for `repl_uninit` changed, the lint was broken before.
The `collapsible_span_lint_calls` and `match_type_on_diag_item` tests have been changed. Both lints were broken when utils was extracted into it's own crate. `match_type_on_diag_item` isn't quite fixed, but it's at least less broken.

Add simd_{round,trunc} intrinsics
LLVM supports many functions from math.h in its IR. Many of these
have SIMD instructions on various platforms. So, let's add round and
trunc so std::arch can use them.
Yes, exact comparison is intentional: rounding must always return a
valid integer-equal value, except for inf/NAN.
Add a note for pre-expansion passes
changelog: none
Just had to turn away a PR for using pre-expansion. I don't think that was the first time. So hopefully this will inform people sooner.

Fix false positives where the map is used before inserting into the map.
Fix false positives where two insertions happen.
Suggest using `if let Entry::Vacant(e) = _.entry(_)` when `or_insert` might be a semantic change
Update docs for unsafe_op_in_unsafe_fn stability.
The unsafe_op_in_unsafe_fn lint was stabilized in #79208, but the bottom of this documentation wasn't updated.
I'm just guessing at the reason here, hopefully it is close to correct. The only discussion I found is https://github.com/rust-lang/rust/issues/71668#issuecomment-730399862 which didn't really explain the thought process behind the decision.

Fix join_paths error display.
On unix, the error from `join_paths` looked like this:
```

This PR changes it to look like this:

Move `std::sys_common::alloc` to new module `std::sys::common`
6b56603e35/library/std/src/sys_common/mod.rs (L7-L13)
It was my impression that the goal for `std::sys` has changed from extracting it into a separate crate to making std work with features. However the fact remains that there is a lot of interdependence between `sys` and `sys_common`, this is because `sys_common` contains two types of code:
- abstractions over the different platform implementations in `std::sys` (for example [`std::sys_common::mutex`](https://github.com/rust-lang/rust/blob/master/library/std/src/sys_common/mutex.rs))
- code shared between platforms (for example [`std::sys_common::alloc`](https://github.com/rust-lang/rust/blob/master/library/std/src/sys_common/alloc.rs))
This PR attempts to address this by adding a new module `common` to `std::sys` which will contain code shared between platforms, `alloc.rs` in this case but more can be moved over in the future.
LLVM supports many functions from math.h in its IR. Many of these have
single-instruction variants on various platforms. So, let's add them so
std::arch can use them.
Yes, exact comparison is intentional: rounding must always return a
valid integer-equal value, except for inf/NAN.
