This is helpful when looking for CGUs where the size estimate isn't a
good indicator of compilation time.

I verified that moving the profiling timer call doesn't affect the
results.

This is mostly me learning the codebase, so feel free to close the PR.
It does have the small benefit that we statically know rustdoc isn't
generating useless `span`s, though.

It's the same as clean::Function.

Replace it instead with `(clean::Function, Option<hir::Defaultness>)`.

It was exactly the same as `is_auto`.

Rustdoc test compiler output color

Fixes rust-lang#72915

We just need to be sure it doesn't break rustdoc doctests' compilation checks. Maybe some other unforeseen consequences too?

`measureme` doesn't have support for custom arg names yet so `arg0` is the CGU name and `arg1` is the estimated size.

Get rid of `highlight::Class::None`

Fix exhaustiveness in case a byte string literal is used at slice type

fixes rust-lang#79048

update rustfmt to v1.4.27

Fixes rust-lang/rustfmt#4528

Get rid of clean::{Method, TyMethod}

They're redundant and almost the same as `clean::Function`.

I needed this for rust-lang#78082, although I forget why.

Remove duplicate `Trait::auto` field

It was exactly the same as `is_auto`.

I found this while working on rust-lang#78082, but it's not required for that PR.
