This rule, added in 49e6db7, overrode a
rule in normalize.css.

https://github.com/rust-lang/rust/blob/49e6db7f3510a99ab3d3723b2430add985629c39/src/librustdoc/html/static/normalize.css#L169-L175

When normalize.css was updated, this rule went away.

necolas/normalize.css@a8edd0c

In 4b402db, when this rule was added, it
was overriding a rule that made all links in docblock get an underline when
hovered. This became redundant when, after reordering the rules,
7585632 changed the pro-underline rule to
exclude the test-arrow link anyway.

Start using `unix_sigpipe` instead of
`rustc_driver::set_sigpipe_handler`.

After this has been merged, we can completely remove
`rustc_driver::set_sigpipe_handler`.

Don't ICE when reporting borrowck errors involving regions from `anonymous_lifetime_in_impl_trait`

The issue here is that when we have:

```
trait Trait<'a> { .. }

fn foo(arg: impl Trait) { .. }
```

The anonymous lifetime `'_` that we generate for `arg: impl Trait` doesn't end up in the argument type (which is a param) but in a where-clause of the function, in a predicate whose self type is that param ty.

Fixes rust-lang#101660

…ismatch, r=lcnr

Delay span bug when we can't map lifetimes back in `collect_trait_impl_trait_tys`

When a lifetime is late-bound in a trait signature, but early-bound in an impl signature, we already emit an error -- however, we also ICE in `collect_trait_impl_trait_tys`, so just delay a bug here.

Fixes rust-lang#103407

rustdoc: Use `unix_sigpipe` instead of `rustc_driver::set_sigpipe_handler`

Do what was already done for `rustc` in rust-lang#102587, namely start using `unix_sigpipe` instead of `rustc_driver::set_sigpipe_handler`.

After this has been merged, we can completely remove `rustc_driver::set_sigpipe_handler`.
