missing space in "rootseparator"
The coverage body_span doesn't always match the function body_span.
Some code cleanup extracted from future (but unfinished) commit to fix
coverage in attr macro functions.
I ran into an error trying to fix dead block coverage and realized the
`coverageinfo` query is getting a different MIR compared to the
codegenned MIR, which can sometimes be a problem during mapgen.

I changed that query to use the `InstandeDef` (which includes the
generic parameter substitutions, prosibly specific to const params)
instead of the `DefId` (without unknown/default const substitutions).
When having the order

```
foo.bar(); // we can now use this method since i32 implements the Foo trait

[...]

impl Foo for i32
```

the `// we can now use this method` comment is less clear to me.

rustdoc: Remove unnecessary `StripItem` wrapper
…efids, r=jyn514,GuillaumeGomez

Minimize amount of fake `DefId`s used in rustdoc

Follow up from rust-lang#84707, which minimizes the amount of fake defids to the smallest amount possible. Every `FakeDefId` that is now used in the rustdoc library must be preserved and can not be replaced with a normal `DefId`.

coverage bug fixes and some refactoring

This replaces the relevant commits (2 and 3) from PR rust-lang#85082, and also corrects an error querying for coverageinfo.

1. `coverageinfo` query needs to use the same MIR as codegen

I ran into an error trying to fix dead block coverage and realized the
`coverageinfo` query is getting a different MIR compared to the
codegenned MIR, which can sometimes be a problem during mapgen.

I changed that query to use the `InstandeDef` (which includes the
generic parameter substitutions, prosibly specific to const params)
instead of the `DefId` (without unknown/default const substitutions).

2. Simplified body_span and filtered span code

  Some code cleanup extracted from future (but unfinished) commit to fix
  coverage in attr macro functions.

3. Spanview needs the relevant body_span used for coverage

The coverage body_span doesn't always match the function body_span.

dbg macro: Discuss use in tests, and slightly clarify

As discussed in a tangent in rust-lang#82778.

I chose to use [semantic newlines](https://rhodesmill.org/brandon/2012/one-sentence-per-line/) in the source text but I don't mind reformatting it.
swap function order for better read flow

I was reading this error message for the first time.

I was a little bit confused when reading that part:
```
foo.bar(); // we can now use this method since i32 implements the Foo trait
```

At the time I was reading `// we can now use this method` I wasn't sure why. It only made sense when reading on. So swapping these parts results in a better read flow.

Fix display for "implementors" section

Just saw this problem when going through docs:

This fix puts it back to normal:

You can see it on the `TryFrom` page for example.
