We render HRTB and the unboxed closure trait sugar (the so-called
"parenthesized" notation) where appropriate. Also address the new
`for` syntax on the old closures.
According to [RFC 344][], methods that return `&[u8]` should have names ending in `bytes`. Though `include_bin!` is a macro not a method, it seems reasonable to follow the convention anyway.
We keep the old name around for now, but trigger a deprecation warning when it is used.

`check::autoderef()` returns a `ty_err` when it fails to infer the type. `probe::probe()` should respect this failure and fail together to prevent further corruption.
Fixes#19692.
Fixes#19583.
Fixes#19297.
The previous behaviour of using the smallest type possible caused LLVM
to treat padding too conservatively, causing poor codegen. This commit
changes the behaviour to use an alignment-sized integer as the
discriminant. This keeps types the same size, but helps LLVM understand
the data structure a little better, resulting in better codegen.
Rename `FPCategory` to `FpCategory` and `Fp* to `*` in order to adhere to the
naming convention
This is a [breaking-change].
Existing code like this:
```
use std::num::{FPCategory, FPNaN};
```
should be adjusted to this:
```
use std::num::FpCategory as Fp
```
In the following code you can use the constants `Fp::Nan`, `Fp::Normal`, etc.

RFC 248? I think you meant RFC 438.
There ain’t an RFC 248, while 438 looks to be what is being referred to:

Chis Morgan has a pretty important documentation fix in #19385 and he hasn't responded in a while to that pull request so I rebased it for him
Closes#19385
Part of #19253
I would have removed this public reexport in #19842, but #19812 hadn't merged (and snapshotted) at the time
In #19407, I changed the codebase to stop utilizing this reexport
[breaking-change]
This is an updated version of #19711. The merge and subsequent rebase on that branch were more trouble than they were worth, so I am just resubmitting the relevant change here.
If this PR is accepted, then #19711 can be closed.

This pull request updates the rustc manual page to represent current state of rustc option handling better. Moved the apparently deprecated options (#19900) to their own section and added all the new codegen options.
A bit unrelatedly, I also updated description of `-O` and `-g` flags to point to the new codegen options rather than old, deprecated ones.
Fixes#20111.
Now that #19448 has landed in a snapshot, we can add proper by-value operator overloads for `HashSet`. The behavior of these operator overloads is consistent with rust-lang/rfcs#235.
