codegen: use new {re,de,}allocator annotations in llvm

This obviates the patch that teaches LLVM internals about
_rust_{re,de}alloc functions by putting annotations directly in the IR
for the optimizer.

The sole test change is required to anchor FileCheck to the body of the
`box_uninitialized` method, so it doesn't see the `allocalign` on
`__rust_alloc` and get mad about the string `alloca` showing up. Since I
was there anyway, I added some checks on the attributes to prove the
right attributes got set.

b8fb6e1032 rustdoc: do not allocate String when writing path full name
No idea if this makes any perf difference, but it just seems like premature
pessimisation to use String when str will do.

```

test vec::bench_next_chunk                               ... bench:         211 ns/iter (+/- 3)
```

The znver2 default impl seems to be slow due to inlining decisions. It goes through `core::array::iter_next_chunk`
which has a deeper call tree.

Fix some broken link fragments.

An exception for link fragments starting with `-` was added in #49590. However, it is not clear what issues were encountered at the time. Perhaps those were fixed in the meantime.

This removes the exception, and fixes a couple of broken links that were skipped due to it.

rustdoc: Add support for `#[rustc_must_implement_one_of]`

This PR adds support for `#[rustc_must_implement_one_of]` attribute added in #92164. There is a desire to eventually use this attribute of `Read`, so making it show up in docs is a good thing.

I "stole" the styling from cfg notes, not sure what would be a proper styling. Currently it looks like this:

130a1df71e codegen: use new {re,de,}allocator annotations in llvm
This obviates the patch that teaches LLVM internals about
_rust_{re,de}alloc functions by putting annotations directly in the IR
for the optimizer.

The sole test change is required to anchor FileCheck to the body of the
`box_uninitialized` method, so it doesn't see the `allocalign` on
`__rust_alloc` and get mad about the string `alloca` showing up. Since I
was there anyway, I added some checks on the attributes to prove the
right attributes got set.

While we're here, we also emit allocator attributes on
__rust_alloc_zeroed. This should allow LLVM to perform more
optimizations for zeroed blocks, and probably fixes #90032. [This
comment](https://github.com/rust-lang/rust/issues/24194#issuecomment-308791157)
mentions "weird UB-like behaviour with bitvec iterators in
rustc_data_structures" so we may need to back this change out if things
go wrong.

The new test cases require LLVM 15, so we copy them into LLVM
14-supporting versions, which we can delete when we drop LLVM 14.

I think this is very useful, especially when there's >1 `impl Trait`, and it just means passing around a bit more info that we already have access to.
