Cleanup: Use rustc's `same_type` for our `same_tys`
This delegates our `same_tys` to [ty::TyS::same_type][same_type] to
remove some duplication.
Our `same_tys` was introduced 4 years ago in #730. Before, it was
building an inference context to be able to call
`can_eq` to compare the types. The `rustc-dev-guide` has some more details
about `can_eq` in [Type Inference -> Trying equality][try_eq].
Now, using the rustc function, we are essentially comparing the `DefId`s
of the given types, which also makes more sense, IMO.
I also confirmed that the FIXME is resolved via a bit of `dbg!`, however
no UI tests seem to have been affected.

Fix cargo tests when running inside the rustlang/rust repo
It seems we hit https://github.com/rust-lang/cargo/issues/5418, so I've applied the suggested solution. Also added some more info when cargo-metadata fails to execute.
(there was no open issue for this)

Replace all remaining occurrences of submodule with subtree

I should have included this in #5686, but forgot about it, so here we go again.

Add regression test for `string_lit_as_bytes` issue
Closes#5619
Before the fix in https://github.com/rust-lang/rust/pull/72637, `string_lit_as_bytes` was incorrectly triggering on the `env!` macro. With the fix merged, this test makes sure that the lint is not triggering anymore.

Give corrected code
This PR adds corrected code for doc examples.
I did this in several commits to facilitate review.
Don't hesitate to tell me if I forgot some.
Also, sometimes I felt it was not necessary to give corrected code, but I maybe wrong.
fixes: #4829
changelog: Improve documentation examples across multiple lints.
New lint: iter_next_slice
Hello, this is a work-in-progress PR for issue: https://github.com/rust-lang/rust-clippy/issues/5572
I have implemented lint to replace `iter().next()` for `slice[index..]` and `array` with `get(index)` and `get(0)` respectively. However since I made a lot of changes, I would like to request some feedback before continuing so that I could fix mistakes.
Thank you!

changelog: implement `iter_next_slice` lint and test, and modify `needless_continues`, `for_loop_over_options_result` UI tests since they have `iter().next()`
Add regression test for endless loop / update `pulldown_cmark`
Closes#4917
This was fixed in pulldown_cmark 0.7.1, specifically raphlinus/pulldown-cmark#438

cargo-ui tests: check that <dir>/src exists before processing test
I forgot that I had fixed this in a PR I closed some days ago (#5643).
Before this change, cargo UI tests could fail when switching between branches if the previous branch had a test that the current branch does not have. The directory is not removed when switching because an ignored `Cargo.lock` file exists, and the code was trying to reach `$DIR/src` unconditionally.
This change will just skip a directory that has no `src` subdirectory.
