update Miri
I had to use a hacked version of josh to create this, so let's be careful with merging this and maybe wait a bit to see if the josh issue becomes more clear. But the history looks good to me, we are not adding duplicates of rustc commits that were previously mirrored to Miri.
Also I want to add some cross-testing of Miri in x.py.
Support raw-dylib functions being used inside inlined functions
Fixes#102714
Issue Details:
When generating the import library for `raw-dylib` symbols, we currently only use the functions and variables declared within the current crate. This works fine if all crates are static libraries or `rlib`s as the generated import library will be contained in the static library or `rlib` itself, but if a dependency is a dynamic library AND the use of a `raw-dylib` function or variable is inlined or part of a generic instantiation then the current crate won't see its dependency's import library and so linking will fail.
Fix Details:
Instead, when we generate the import library for a `dylib` or `bin` crate, we will now generate it for the symbols both for the current crate and all upstream crates. We do this in two steps so that the import library for the current crate is passed into the linker first, thus it is preferred if there are any ambiguous symbols.
rustdoc: Use `unix_sigpipe` instead of `rustc_driver::set_sigpipe_handler`
Do what was already done for `rustc` in #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`.

rustdoc: remove redundant CSS `a.test-arrow:hover`
In 4b402dbe69, 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, 7585632052 changed the pro-underline rule to exclude the test-arrow link anyway.
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#103407
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#101660

Only apply `ProceduralMasquerade` hack to older versions of `rental`
The latest version of `rental` (v0.5.6) contains a fix that allows it to
compile without relying on the pretty-print back-compat hack.
Hopefully, there are no longer any crates relying on the affected
versions of the (much less popular) `procedural-masquerade` crate. This
should allow us to target the pretty-print back-compat hack specifically
to older versions of `rental`, and specifically mention upgrading to
`rental` v0.5.6 in the lint message.
Sort tests at compile time, not at startup
Recently, another Miri user was trying to run `cargo miri test` on the crate `iced-x86` with `--features=code_asm,mvex`. This configuration has a startup time of ~18 minutes. That's ~18 minutes before any tests even start to run. The fact that this crate has over 26,000 tests and Miri is slow makes a lot of code which is otherwise a bit sloppy but fine into a huge runtime issue.
Sorting the tests when the test harness is created instead of at startup time knocks just under 4 minutes out of those ~18 minutes. I have ways to remove most of the rest of the startup time, but this change requires coordinating changes of both the compiler and libtest, so I'm sending it separately.
(except for doctests, because there is no compile-time harness)

The code headers are always h3 or h4, which don't have border-bottom by default anyway.

Fix wrapped valid-range handling in ty_find_init_error
Rust's niche handling allows for wrapping valid ranges with end < start;
for instance, a valid range with start=43 and end=41 means a niche of
42. Most places in the compiler handle this correctly, but
`ty_find_init_error` assumed that `lo > 0` means the type cannot contain a
zero.
Fix it to handle wrapping ranges.
rustdoc: do not filter out cross-crate `Self: Sized` bounds
All type parameters **except `Self`** are implicitly `Sized` ([via](https://doc.rust-lang.org/nightly/std/marker/trait.Sized.html)). Previously, we disregarded the exception of `Self` and omitted cross-crate `Sized` bounds of *any* type parameter *including* `Self` when rendering.
From now on, we *do* render cross-crate `Self: Sized` bounds.
Most notably, in `std` we now finally properly render the `Sized` bound of the `Clone` trait as well as the `Self: Sized` bound on `Iterator::map`.
Fixes#24183.

Upgrade dist-mips*-linux to ubuntu:22.04 + crosstool-ng
These have no change in compatibility, still Linux 4.4 and glibc 2.23.
The main motivation for upgrading is that LLVM 16 will require at least GCC 7.1. Using crosstool-ng lets us choose our own toolchain versions, and then the Ubuntu version doesn't matter so much, just for the host compilation while we cross-compile.
