Add built in PSP target
This adds a new target, `mipsel-sony-psp`, corresponding to the Sony PSP. The linker script is necessary to handle special sections, which are required by the target. This has been tested with my [rust-psp] crate and I can confirm it works as intended.
The linker script is taken from [here]. It has been slightly adapted to work with rust and LLD.
The `stdarch` submodule was also updated in order for `libcore` to build successfully.

Don't ICE on missing `Unsize` impl
Previously code of the form
```rust
#![feature(unsize, dispatch_from_dyn)]
use std::marker::Unsize;
use std::ops::DispatchFromDyn;
pub struct Foo<'a, T: ?Sized> {
_inner: &'a &'a T,
}
impl<'a, T: ?Sized + Unsize<U>, U: ?Sized> DispatchFromDyn<Foo<'a, U>> for Foo<'a, T> {}
```
would generate an ICE due to the missing `Unsize` impl being run through the `suggest_change_mut` suggestion. This PR adds an early exit and a pointer to the appropriate docs regarding `Unsize` instead:
```
error[E0277]: the trait bound `&'a T: std::marker::Unsize<&'a U>` is not satisfied
--> src/test/ui/issues/issue-71036.rs:11:1

= note: all implementations of `Unsize` are provided automatically by the compiler, see <https://doc.rust-lang.org/stable/std/marker/trait.Unsize.html> for more information

use `require_lang_item` over `unwrap`.
Does not yet replace all uses of `lang_items\(\)\.*\.unwrap\(\)`, as there are more
than I expected :sweat_smile:
Fixes #72099
r? @RalfJung
*edit: The goal of this this PR is to change ICE from missing lang items to a fatal error.*

Warn against thread::sleep in async fn
I've seen `thread::sleep` wrecking havoc in async servers. There's already an [issue for clippy](https://github.com/rust-lang/rust-clippy/issues/4377), but the std docs could warn against it too.

Document From trait for Option implementations

Be slightly more precise about any::type_name()'s guarantees.
The first commit in this PR rephrases the current documentation for `any::type_name()` to be a little more specific about the guarantees (or lack thereof) that this function makes. The second commit explicitly documents that lifetimes are currently not included in the output (since this bit me particularly hard recently).

Pointer printing: do not print 0 offset

`prefix` should not be mutable.
Change the process from for loop to find, which makes the `prefix` able to be immutable.

Modify SimplifyArmIdentity so it can trigger on mir-opt-level=1
I also added test cases to make sure the optimization can fire on all of
these cases:
```rust
fn case_1(o: Option<u8>) -> Option<u8> {
match o {
Some(u) => Some(u),
None => None,
}
}
fn case2(r: Result<u8, i32>) -> Result<u8, i32> {
match r {
Ok(u) => Ok(u),
Err(i) => Err(i),
}
}
fn case3(r: Result<u8, i32>) -> Result<u8, i32> {
let u = r?;
Ok(u)
}
```
Without MIR inlining, this still does not completely optimize away the
`?` operator because the `Try::into_result()`, `From::from()` and
`Try::from_error()` calls still exist. This does move us a bit closer to
that goal though because:
- We can now run the pass on mir-opt-level=1
- We no longer depend on the copy propagation pass running which is
unlikely to stabilize anytime soon.
Fixes #66855

bootstrap: remove lldb dist packaging
The lldb-preview rustup package is missing on every single target, and has never been shipped beyond x86_64-apple-darwin. It was removed in #62592 which landed around a year ago, and there's not been demand that we re-enable it since, so we're now removing support entirely to cleanup the code a bit.
The hope is that this will also kill the useless "lldb-preview" row on https://rust-lang.github.io/rustup-components-history/.

r=Amanieu
Make `RawVec::grow` mostly non-generic.
`cargo-llvm-lines` shows that, in various benchmarks, `RawVec::grow` is
instantiated 10s or 100s of times and accounts for 1-8% of lines of
generated LLVM IR.
This commit moves most of `RawVec::grow` into a separate function that
isn't parameterized by `T`, which means it doesn't need to be
instantiated many times. This reduces compile time significantly.
