Avoid repeated re-initialization of the BufReader buffer

Fixes https://github.com/rust-lang/rust/issues/102727

We accidentally removed this in https://github.com/rust-lang/rust/pull/98748. It looks so redundant. But it isn't.

The default `Read::read_buf` will defensively initialize the whole buffer, if any of it is indicated to be uninitialized. In uses where reads from the wrapped `Read` impl completely fill the `BufReader`, `initialized` and `filled` are the same, and this extra member isn't required. But in the reported issue, the `BufReader` wraps a `Read` impl which will _never_ fill the whole buffer. So the default `Read::read_buf` implementation repeatedly re-initializes the extra space in the buffer.

This adds back the extra `initialized` member, which ensures that the default `Read::read_buf` only zero-initialized the buffer once, and I've tried to add a comment which explains this whole situation.

let-else: test else block with non-never uninhabited type

let else currently does not allow uninhabited types for the `else` block that aren't `!`. One can maybe think about relaxing this in the future, but if it is done, it should be an explicit choice and not an unexpected side effect of e.g. a refactor. Thus, I'm extending a test that will fail if the behaviour changes.

Disable compressed debug sections on i586-gnu

Compressed debug is enabled by default for gas (assembly) on Linux/x86
targets, and we started building our own in #102530, but that made our
`compiler_builtins` incompatible with binutils < 2.32. Add an explicit
option to disable that in our crosstool-ng config. Fixes #102703.

rustdoc: remove unused CSS `.docblock a:not(.srclink)`

This selector was added in c7312fbae4979c6d4fdfbd1f55a71cd47d82a480, because the list of impl items could be nested below `docblock`.

Now that rustdoc toggles have been switched to `<details>`, there shouldn't be any need to put things inside docblock containers just to give them disclosure toggles.

When these rules were added in 4fd061c426902b0904c65e64a3780b21f9ab3afb (yeah, that's the very first commit of rustdoc_ng), `.item-list` was a `<ul>`, and this would override the default style for that tag.

In c1b1d6804bfce1aee3a95b3cbff3eaeb15bad9a4, it was changed to use a `<div>` tag, so these rules are both no-ops.
