reference counted pointer -> reference-counted pointer

`alloc::slice` uses `core::slice` functions, documentation are copied
from there and the links as well without resolution. `crate::ptr...`
cannot be resolved in `alloc::slice`, but `ptr` itself is imported in
both `alloc::slice` and `core::slice`, so we used that instead.

Fixes rust-lang#75930

This changes the tokens seen by a proc-macro. However, ising a `#[cfg]` attribute
on a generic paramter is unusual, and combining it with a proc-macro
derive is probably even more unusual. I don't expect this to cause any
breakage.

StringReader is an intornal abstraction which at the moment changes a
lot, so these unit tests cause quite a bit of friction.

Moving them to rustc_lexer and more ingerated-testing style should
make them much less annoying, hopefully without decreasing their
usefulness much.

Note that coloncolon tests are removed (it's unclear what those are
testing).

\r\n tests are removed as well, as we normalize line endings even
before lexing.

This commit removes the obsolete printer and replaces all uses of it
with `FmtPrinter`. Of the replaced uses, all but one use was in `debug!`
logging, two cases were notable:

- `MonoItem::to_string` is used in `-Z print-mono-items` and therefore
  affects the output of all codegen-units tests.
- `DefPathBasedNames` was used in `librustc_codegen_llvm/type_of.rs`
  with `LLVMStructCreateNamed` and that'll now get different values, but
  this should result in no functional change.

…ed()

These are unsafe variants of the non-unchecked functions and don't do
any bounds checking.

For the time being these are not public and only a preparation for the
following commit. Making it public and stabilization can follow later
and be discussed in rust-lang#76014 .

…s during construction

LLVM can't figure out in

    let rem = self.len() % chunk_size;
    let len = self.len() - rem;
    let (fst, snd) = self.split_at(len);

and

    let rem = self.len() % chunk_size;
    let (fst, snd) = self.split_at(rem);

that the index passed to split_at() is smaller than the slice length and
adds a bounds check plus panic for it.

Apart from removing the overhead of the bounds check this also allows
LLVM to optimize code around the ChunksExact iterator better.

Thanks to Ivan Tham, who gave the majority of these suggestions during
their review.

ty: remove obsolete pretty printer

Fixes rust-lang#61139.

This PR removes the obsolete printer and replaces all uses of it with `FmtPrinter`. Of the replaced uses, all but one use was in `debug!` logging, two cases were notable:

- `MonoItem::to_string` is used in `-Z print-mono-items` and therefore affects the output of all codegen-units tests (which have been updated).
- `DefPathBasedNames` was used in `librustc_codegen_llvm/type_of.rs` with `LLVMStructCreateNamed` and that'll now get different values, but nothing will break as a result of this.
