* Both enums already derived `Copy`, but storing them in any
struct/container would prevent implementing `Clone` for said
struct/container even though they should be clonable.
* Also add PartialEq and Eq for good measure.
It's quite possible that small programs don't use all of jemalloc, and building
with -ffunction-sections and -fdata-sections allows the linker (via
--gc-sections) to strip out all unused code at link time. This decreases the
size of a "hello world" executable for me from 716K to 482K with no measurable
impact on link time. After this patch jemalloc is still the largest portion of
our hello world executables, but this helps cut down on the size at least
somewhat!
#20075 introduced a bug where unmarked code fences weren't considered as doctests. This PR fixes the logic.

This passed `check-stage1-rustdoc`, and I manually checked that:
``` rust
//! ```
//! println!("Hello")
//! ```
//!
//! ``` rust
//! println!("Hello")
//! ```
//!
//! ``` sh
//! println!("Hello")
//! ```
//!
//! ``` ignore
//! println!("Hello")
//! ```
```
Generated:
``` rust
running 3 tests
test _2 ... ignored
test _0 ... ok
test _1 ... ok
```
I'd love to add that as a test, but I have no idea how to do that with our testing infrastructure. If anyone knows how, do let me know!

Add support for all variants of ast::WherePredicate in clean/mod.rs. Fixes#20048, but will need modification when EqualityPredicates are fully implemented in #20041.
... really this time `:)`
I went for the simpler fix after all since it turned out to become a bit too complicated to extract the current iteration value from its containing `Option` with the different memory layouts it can have. It's also what we already do for match bindings.
I also extended the new test case to include the "simple identifier" case.
Fixes#20127, fixes#19732

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
