rustdoc: don't try to get a DefId for a Def that doesn't have one
Fixes https://github.com/rust-lang/rust/issues/58054
The compiler allows you to write a `use` statement for a built-in non-macro attribute, since `use proc_macro` can apply to both the `proc_macro` crate and the `#[proc_macro]` attribute. However, if you write a use statement for something that *doesn't* have this crossover, rustdoc will try to use it the same way as anything else... which resulted in an ICE because it tried to pull a DefId for something that didn't have one. This PR makes rustdoc skip those lookups when it encounters them, allowing it to properly process and render these imports.
Don't try to clean predicates involving ReErased
There's nothing to render when we have a bound involving ReErased (either
a type or region outliving it), so we don't attempt to generate a clean
WherePredicate
Fixes#57806
I haven't been able to come up with a minimized reproduction for the issue, but I've confirmed that this allows the docs to build for `parqet-rs`

Add support for trait-objects without a principal
The hard-error version of #56481 - should be merged after we do something about the `traitobject` crate.
Fixes#33140.
Fixes#57057.

This commit improves the calculation of code spans for intra-doc
resolution failures. All sugared doc comments should now have the
correct spans, including those where the comment is longer than the
docs.
It also fixes an issue where the spans were calculated incorrectly for
certain unsugared doc comments. The diagnostic will now always use the
span of the attributes, as originally intended.
Fixes#55964.
53956 panic on include bytes of own file
fix#53956
When using `include_bytes!` on a source file in the project, compiler would panic on subsequent compilations because `expand_include_bytes` would overwrite files in the source_map with no source. This PR changes `expand_include_bytes` to check source_map and use the already existing src, if any.
`CrateRoot` -> `PathRoot`, `::` doesn't necessarily mean crate root now
`SelfValue` -> `SelfLower`, `SelfType` -> `SelfUpper`, both `self` and `Self` can be used in type and value namespaces now
