Switch transmute_ptr_to_ptr to "pedantic" class.

Per discussion in https://github.com/rust-lang/rust-clippy/issues/6372, this lint has significant false positives.

changelog: transmute_ptr_to_ptr defaults to "allow".

bootstrap: Restore missing --bulk-dirs for rust-docs, rustc-docs

The `--bulk-dirs` argument was removed for rust-docs in commit c768ce1384 and rustc-docs in commit 8ca46fc7a8 (#79788), presumably by mistake; that slowed down installation of rust-docs from under a second to some twenty *minutes*.  Restoring `--bulk-dirs` reverses this slowdown.

Fixes #80684.

e8eb691c1f Use arrayvec 0.7, drop smallvec 0.6
With the arrival of min const generics, many alt-vec libraries have
updated to use it in some way and arrayvec is no exception. Use the
latest with minor refactoring.

Also, rustc_workspace_hack is the only user of smallvec 0.6 in the
entire tree, so drop it.

Rollup merge of #84393 - GuillaumeGomez:better-open-handling, r=jyn514
Support `x.py doc std --open`

I usually run this command:

```
./x.py doc std --stage 1 --jobs 8
```

Then I gave a try to `--open` and realized it wasn't working. I finally realized it was simply because it was only handling paths starting with `library`. This PR allows to handle both kinds of paths.

Rollup merge of #84380 - Smittyvb:rdoc-title-order, r=jsha
Write Rustdoc titles like "x in crate::mod - Rust"

This makes Rustdoc titles for items be like "Widget in cratename::blah::foo - Rust". Titles for modules and other non-items are unchanged, and still read like "cratename::blah::foo - Rust". This makes managing several open Rustdoc tabs easier.

![A screenshot of several open Rustdoc tabs](https://user-images.githubusercontent.com/10530973/115457675-d608f180-a1f2-11eb-87a8-838a32b4e3f7.png)

This also adds some tests for the new title behavior.

Closes #84371.

Rollup merge of #84251 - RalfJung:non-zero-const-since, r=kennytm
fix 'const-stable since' for NonZeroU*::new_unchecked

For the unsigned `NonZero` types, `new_unchecked` was const-stable from the start with https://github.com/rust-lang/rust/pull/50808. Fix the docs to accurately reflect that.

I think this `since` is also incorrect:
```rust
            #[stable(feature = "from_nonzero", since = "1.31.0")]
            impl From<$Ty> for $Int {
```
The signed nonzero types were only stabilized in 1.34, so that `From` impl certainly didn't exist before. But I had enough of digging through git histories after I figured out when `new_unchecked` became const-stable...^^

Rollup merge of #84212 - CDirkx:void, r=m-ou-se
Replace `Void` in `sys` with never type

This PR replaces several occurrences in `sys` of the type `enum Void {}` with the Rust never type (`!`).
The name `Void` is unfortunate because in other languages (C etc.) it refers to a unit type, not an uninhabited type.

Note that the previous stabilization of the never type was reverted, however all uses here are implementation details and not publicly visible.

Rollup merge of #84119 - CDirkx:vxworks, r=m-ou-se
Move `sys::vxworks` code to `sys::unix`

Follow-up to #77666, `sys::vxworks` is almost identical to `sys::unix`, the only differences are the `rand`, `thread_local_dtor`, and `process` implementation. Since `vxworks` is `target_family = unix` anyway, there is no reason for the code not to live inside of `sys::unix` like all the other unix-OSes.

de2a4601ab rustc: Use LLVM's new saturating float-to-int intrinsics
This commit updates rustc, with an applicable LLVM version, to use
LLVM's new `llvm.fpto{u,s}i.sat.*.*` intrinsics to implement saturating
floating-point-to-int conversions. This results in a little bit tighter
codegen for x86/x86_64, but the main purpose of this is to prepare for
upcoming changes to the WebAssembly backend in LLVM where wasm's
saturating float-to-int instructions will now be implemented with these
intrinsics.

This change allows simplifying a good deal of surrounding code, namely
removing a lot of wasm-specific behavior. WebAssembly no longer has any
special-casing of saturating arithmetic instructions and the need for
`fptoint_may_trap` is gone and all handling code for that is now
removed. This means that the only wasm-specific logic is in the
`fpto{s,u}i` instructions which only get used for "out of bounds is
undefined behavior". This does mean that for the WebAssembly target
specifically the Rust compiler will no longer be 100% compatible with
pre-LLVM 12 versions, but it seems like that's unlikely to be relied on
by too many folks.

Note that this change does immediately regress the codegen of saturating
float-to-int casts on WebAssembly due to the specialization of the LLVM
intrinsic not being present in our LLVM fork just yet. I'll be following
up with an LLVM update to pull in those patches, but affects a few other
SIMD things in flight for WebAssembly so I wanted to separate this change.

Eventually the entire `cast_float_to_int` function can be removed when
LLVM 12 is the minimum version, but that will require sinking the
complexity of it into other backends such as Cranelfit.

Add lint to check for boolean comparison in assert macro calls

This PR adds a lint to check if an assert macro is using a boolean as "comparison value". For example:

```rust
assert_eq!("a".is_empty(), false);
```

Could be rewritten as:

```rust
assert!(!"a".is_empty());
```

PS: The dev guidelines are amazing. Thanks a lot for writing them!
