461e807801 Auto merge of #94995 - luojia65:riscv-more-features, r=Amanieu
Support more RISC-V backend features on rustc compiler

This pull request adds the following RISC-V compiler features:

- V for vector extension
- Zfinx, Zdinx, Zhinx and Zhinxmin float in integer register extensions
- Zfh, Zfhmin 16-bit float pointer extensions
- Zbkb, Zkbc, Zbkc, Zk* cryptography extensions

It matches name in LLVM feature and is_riscv_feature_detected!. In this case we can use `#[target_feature]` on new RISC-V features. Ref: https://github.com/rust-lang/stdarch/pull/1263#pullrequestreview-825891905

Use `rustc --print target-features` under any RISC-V target (or with `--target`) to check the features the rustc compiler support.

Rollup merge of #94951 - est31:irrefutable_let_chain_patterns, r=estebank
Extend the irrefutable_let_patterns lint to let chains

Implements the suggestion from https://github.com/rust-lang/rust/pull/94927#issuecomment-1067078300

We only look for complete suffixes or prefixes of irrefutable let patterns, so
that an irrefutable let pattern in a chain surrounded by refutable ones is
not linted, as it is an useful pattern that has no low-cost replacement (unlike suffixes or prefixes which can just be copied outside of the `if`: either into the `if`'s block, or the block surrounding the `if`).
If all patterns in a let chain are irrefutable, we lint as well.

Depends on #94958 ~~so I included it into the PR for now~~ *which has been merged since*.

Rollup merge of #94868 - dtolnay:noblock, r=Dylan-DPC
Format core and std macro rules, removing needless surrounding blocks

Many of the asserting and printing macros in `core` and `std` are written with prehistoric-looking formatting, like this:

335ffbfa54/library/std/src/macros.rs (L96-L101)

In modern Rust style this would conventionally be written as follows instead, always using braces and a trailing semicolon on the macro arms:

af53809c87/library/std/src/macros.rs (L98-L105)

Getting rid of the unneeded braces inside the expansion reduces extraneous indentation in macro-expanded code. For example:

```rust
println!("repro {}", true);
```

```rust
// before:

{
    ::std::io::_print(
        ::core::fmt::Arguments::new_v1(
            &["repro ", "\n"],
            &[::core::fmt::ArgumentV1::new_display(&true)],
        ),
    );
};
```

```rust
// after:

::std::io::_print(
    ::core::fmt::Arguments::new_v1(
        &["repro ", "\n"],
        &[::core::fmt::ArgumentV1::new_display(&true)],
    ),
);
```

0dcb1754b6 solaris build environment should include libsendfile/liblgrp
As of version 0.2.120 of the libc crate, the solaris target now requires
some additional libraries to be present in the sysroot.  Note that the
solaris target doesn't really build against files from Solaris, but
rather against some files from DilOS (a platform similar to both Solaris
and illumos).  Pull in the extra libraries and their compilation links
from that apt repository.
