This commit partially reverts rust-lang#868 to restore the intrinsics to their original implementation to avoid breaking changes. This is done while rust-lang/rust#73166 is running through crater, and should unblock rust-lang/rust#74482.

Clean up some of the pkgsrc Makefile, there's still lots in here that
should just be deleted though. Switch SunOS to the illumos bootstrap
by default.
Version 1.48.0 (2020-11-19)
==========================
Language
--------
- [The `unsafe` keyword is now syntactically permitted on modules.][75857] This
is still rejected *semantically*, but can now be parsed by procedural macros.
Compiler
--------
- [Stabilised the `-C link-self-contained=<yes|no>` compiler flag.][76158] This tells
`rustc` whether to link its own C runtime and libraries or to rely on a external
linker to find them. (Supported only on `windows-gnu`, `linux-musl`, and `wasi` platforms.)
- [You can now use `-C target-feature=+crt-static` on `linux-gnu` targets.][77386]
Note: If you're using cargo you must explicitly pass the `--target` flag.
- [Added tier 2\* support for `aarch64-unknown-linux-musl`.][76420]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`io::Write` is now implemented for `&ChildStdin` `&Sink`, `&Stdout`,
and `&Stderr`.][76275]
- [All arrays of any length now implement `TryFrom<Vec<T>>`.][76310]
- [The `matches!` macro now supports having a trailing comma.][74880]
- [`Vec<A>` now implements `PartialEq<[B]>` where `A: PartialEq<B>`.][74194]
- [The `RefCell::{replace, replace_with, clone}` methods now all use `#[track_caller]`.][77055]
Stabilized APIs
---------------
- [`slice::as_ptr_range`]
- [`slice::as_mut_ptr_range`]
- [`VecDeque::make_contiguous`]
- [`future::pending`]
- [`future::ready`]
The following previously stable methods are now `const fn`'s:
- [`Option::is_some`]
- [`Option::is_none`]
- [`Option::as_ref`]
- [`Result::is_ok`]
- [`Result::is_err`]
- [`Result::as_ref`]
- [`Ordering::reverse`]
- [`Ordering::then`]
Cargo
-----
Rustdoc
-------
- [You can now link to items in `rustdoc` using the intra-doc link
syntax.][74430] E.g. ``/// Uses [`std::future`]`` will automatically generate
a link to `std::future`'s documentation. See ["Linking to items by
name"][intradoc-links] for more information.
- [You can now specify `#[doc(alias = "<alias>")]` on items to add search aliases
when searching through `rustdoc`'s UI.][75740]
Compatibility Notes
-------------------
- [Promotion of references to `'static` lifetime inside `const fn` now follows the
same rules as inside a `fn` body.][75502] In particular, `&foo()` will not be
promoted to `'static` lifetime any more inside `const fn`s.
- [Associated type bindings on trait objects are now verified to meet the bounds
declared on the trait when checking that they implement the trait.][27675]
- [When trait bounds on associated types or opaque types are ambiguous, the
compiler no longer makes an arbitrary choice on which bound to use.][54121]
- [Fixed recursive nonterminals not being expanded in macros during
pretty-print/reparse check.][77153] This may cause errors if your macro wasn't
correctly handling recursive nonterminal tokens.
- [`&mut` references to non zero-sized types are no longer promoted.][75585]
- [`rustc` will now warn if you use attributes like `#[link_name]` or `#[cold]`
in places where they have no effect.][73461]
- [Updated `_mm256_extract_epi8` and `_mm256_extract_epi16` signatures in
`arch::{x86, x86_64}` to return `i32` to match the vendor signatures.][73166]
- [`mem::uninitialized` will now panic if any inner types inside a struct or enum
disallow zero-initialization.][71274]
- [`#[target_feature]` will now error if used in a place where it has no effect.][78143]
- [Foreign exceptions are now caught by `catch_unwind` and will cause an abort.][70212]
Note: This behaviour is not guaranteed and is still considered undefined behaviour,
see the [`catch_unwind`] documentation for further information.
Internal Only
-------------
These changes provide no direct user facing benefits, but represent significant
improvements to the internals and overall performance of rustc and
related tools.
- [Building `rustc` from source now uses `ninja` by default over `make`.][74922]
You can continue building with `make` by setting `ninja=false` in
your `config.toml`.
- [cg_llvm: `fewer_names` in `uncached_llvm_type`][76030]
- [Made `ensure_sufficient_stack()` non-generic][76680]

to NetBSD/pkgsrc

Jan 1, 2021
Pkgsrc changes:
* Compensate for files being moved around upstream.
* Introduce optional, on-by-default semi-static building of cargo,
using the internal curl and openssl sources. This reduces the dynamic
dependencies of cargo and therefore the rust package itself.
Ref. options.mk.
* The 1.47.0 bootstrap kits have been re-built with the above option
turned on, so no longer depends on curl or openssl from pkgsrc and/or
from earlier OS or pkgsrc versions. This should hopefully fix
installation of rust with non-default PREFIX, ref. PR#54453.

This PR changes the public signature of the following functions in
core::arch::{x86, x86_64}:This change is desired so that these signatures
_mm_extract_epi8and_mm_extract_epi16A crater run revealed only a single breakage. The vektor crate copied the incorrect signatures in
coreexactly to their own crate. The functions don't seem to be used by anyone anywhere.Actual breakage is not expected, since due to the nature of the functions, users would generally write
_mm256_extract_epi8(...) as u8or_mm256_extract_epi16(...) as u16.See rust-lang/stdarch#868. Note that the changes from that stdarch PR have already partially landed in core after rust-lang/stdarch#878. This PR is now only about the remaining changes.
