Rollup merge of #59102 - newpavlov:duration_float, r=alexcrichton
Consistent naming for duration_float methods and additional f32 methods

`duration_float` tracking issue: #54361

New list of methods:
- `as_secs_f64(&self) -> f64`
- `as_secs_f32(&self) -> f32`
- `from_secs_f64(secs: f64) -> Duration`
- `from_secs_f32(secs: f32) -> Duration`
- `mul_f64(self, rhs: f64) -> Duration`
- `mul_f32(self, rhs: f32) -> Duration`
- `div_f64(self, rhs: f64) -> Duration`
- `div_f32(self, rhs: f64) -> Duration`
- `div_duration_f64(self, rhs: Duration) -> f64`
- `div_duration_f32(self, rhs: Duration) -> f32`

With [`num_traits::Float`](https://docs.rs/num-traits/0.2.6/num_traits/float/trait.Float.html) we could've reduced number of methods by factor of two, but unfortunately it's not part of `std`.

Avoid some common false positives in intra doc link checking

The empty string case is never going to be a link. The numeric case may be a link, but if it were it would have resolved locally. It's more likely the makeshift markdown footnote notation (`[0]`, etc)

Rollup merge of #59036 - dlrobertson:fix_59021, r=estebank
Fix ICE in MIR pretty printing

A `Def::Variant` should be considered as a function in mir pretty
printing. Each variant has a constructor that we must print.

Given the following enum definition:

```rust
pub enum TestMe {
    X(usize),
}
```

We will need to generate a constructor for the variant `X` with a
signature that looks something like the following:

```
fn TestMe::X(_1: usize) -> TestMe;
```

Rollup merge of #59025 - aoikonomopoulos:issue-57924, r=varkor
Fix generic argument lookup for Self

Rewrite the SelfCtor early and use the replacement Def when
calculating the path_segs.

Note that this also changes which def is seen by the code that
computes user_self_ty and is_alias_variant_ctor; I don't see a
immediate issue with that, but I'm not 100% clear on the
implications.

Fixes #57924

Rollup merge of #58976 - phil-opp:patch-2, r=alexcrichton
Default to integrated `rust-lld` linker for UEFI targets

The `x86_64-unknown-uefi` target was added in https://github.com/rust-lang/rust/pull/56769 with the linker defaulting to `lld-link`. This means that a system linker with that name is required for linking.

I think defaulting to `rust-lld`, which is shipped with Rust, is a better default for the following reasons:

- Most systems don't have `lld-link` installed, so it forces users to install it first.
- The naming of LLD executables is not standarized, so users often need to create an additional symlink before things work. For example, on Ubuntu `apt install lld` leads to an executable named `lld-link-6.0`.
- We already default to `rust-lld` for [many targets](https://github.com/rust-lang/rust/search?utf8=%E2%9C%93&q=rust-lld&type=), including embedded and WASM targets, so doing the same for UEFI crates seems consistent to me. (It even seems like `x86_64-unknown-uefi` is the [only target](https://github.com/rust-lang/rust/search?q=lld-link&unscoped_q=lld-link) that uses `lld-link`.)

cc @dvdhrm who added the target and @kkk669 who [proposed to use `rust-lld`](https://github.com/rust-lang/rust/pull/56769#issuecomment-461119648).

Rollup merge of #58949 - jethrogb:jb/sgx-thread-id, r=joshtriplett
SGX target: Expose thread id function in os module

In order to call `std::os::fortanix_sgx::usercalls::send`, you need the thread id. This exposes it through another function in `std::os::fortanix_sgx`.

I looked at how other platforms do this. On Windows and `cfg(unix)` you can get the OS handle from a `thread::JoinHandle`, but that's not sufficient, I need it for a `thread::Thread`. In the future, this functionality could be added to `thread::Thread` and this platform can follow suit.

MIPS: add r6 support

MIPS r6 is quite different with the previous version.
It use some new target triples:
  mipsisa32r6-unknown-linux-gnu
  mipsisa32r6el-unknown-linux-gnu
  mipsisa64r6-unknown-linux-gnuabi64
  mipsisa64r6el-unknown-linux-gnuabi64

This patch has been tested with Debian Port for mips64r6el,
and the support of these triples also is included in llvm:

Rollup merge of #58933 - SimonSapin:alloc-prelude-v1, r=Amanieu
Move alloc::prelude::* to alloc::prelude::v1, make alloc a subset of std

This was one of the unresolved questions of https://github.com/rust-lang/rfcs/pull/2480. As the RFC says this is maybe not useful in the sense that we are unlikely to ever have a second version, but making the crate a true subset makes one less issue to think about if we stabilize it and later want to merge standard library crates and have Cargo feature flags to enable or disable parts of the `std` crate.

See also discussion in https://github.com/rust-lang/rust/pull/58175.

Also rename the feature gate and point to a dedicated tracking issue: https://github.com/rust-lang/rust/issues/58935

Rollup merge of #58901 - ebarnard:just-copying, r=sfackler
Change `std::fs::copy` to use `copyfile` on MacOS and iOS

`copyfile` on MacOS is similar to `CopyFileEx` on Windows. It supports copying resource forks, extended attributes, and file ACLs, none of which are copied by the current generic unix implementation.

The API is available from MacOS 10.7 and iOS 4.3 (and possibly earlier but I haven't checked).

Closes #58895.

std: Spin for a global malloc lock on wasm32

There's lots of comments in the code, but the main gist of this commit
is that the acquisition of the global malloc lock on the
`wasm32-unknown-unknown` target when threads are enabled will not spin
on contention rather than block.

appveyor: Use VS2017 for all our images

Originally added in #55935 to test build times, this was reverted
in #56201 due to a belief that it caused the exit code 259 spurious
errors. We've since learned, however, that the 259 exit code is likely
not related to this image update as we're getting it in a number of
locations now.

VS2017 looks like it may be required to compile LLVm in the near future,
notably discovered by #58408 where we attempted to update LLVM.

Refactor ppaux out of existence.

A long-time coming, this PR reorganizes and rewrites the pretty-printing architecture of rustc, specifically the parts that involve the typesystem (which used to be in `rustc::util::ppaux`).

*Note: these commits used to be in #57967 before being split off.*

The new API (i.e. the `Printer` and `PrettyPrint` traits) is in `rustc::ty::print`.

Design points, roughly:
* using associated types in `Printer` to allow building e.g. an AST, not just printing as a side-effect
* several overloading points for implementers of `PrettyPrinter`, e.g. how `<...>` is printed
* for `fmt::Display` impls, the value to print is lifted to the `ty::tls` `tcx`, and everything after that stays within the `ty::print` API, which requires `'tcx` to match between values and the printer's `tcx`, without going through `fmt::Display` again

Most of the behavior is unchanged, except for a few details, which should be clear from the test changes.

5303c1b90b Remove restriction on isize/usize in repr(simd)
As discussed in #55078, there's no known reason for this restriction.

It's unlikely that repr(simd) will be stabilized in its current form, but
might as well remove some restrictions on it.

This removes the branch in `is_machine` which returns false for these types.
`is_machine` is only used for the repr(simd) type validation check.
